How to change chart series line color in Dojo? - dojo

I am now using Dojo to show a line chart. but I don't know how to change the series line color, would anyone help? thx.
var chart1 = new dc.Chart("test1");
chart1.addPlot("default", { type: "Default", lines: true, markers: true, tension: 1 });
chart1.addAxis("x", { majorTick: { stroke: "black", length: 5 }, minorTick: { stroke: "black", length: 1} });
chart1.addAxis("y", { vertical: true, majorTick: { stroke: "black", length: 5 }, minorTick: { stroke: "black", length: 1} });
chart1.addSeries("Series A", [{ x: 0.5, y: 5 }, { x: 1.5, y: 1.5 }, { x: 2, y: 9 }, { x: 5, y: 0.3}]);
chart1.addSeries("Series B", [{ x: 0.3, y: 8 }, { x: 4, y: 6, tooltip: "Custom tooltip" }, { x: 5.5, y: 2}]);
chart1.addSeries("Series C", [{ x: 0.8, y: 6 }, { x: 8, y: 1, tooltip: "Custom tooltip" }, { x: 7, y: 2}]);
chart1.addSeries("Series D", [{ x: 0.1,y: 5}, { x: 2, y: 3, tooltip: "Custom tooltip" }, { x: 4, y: 5}]);
var anim1a = new dc.action2d.Magnify(chart1, "default");
var anim1b = new dc.action2d.Tooltip(chart1, "default");
chart1.render();
for Series A, Series B,Series C,Series D,I want to use my-defined color to show them, anyone can help?

You can probably also provide the color in your series for it to be used by the plot. Something like the following:
chart1.addSeries("Series A",
[{ x: 0.5, y: 5 }, { x: 1.5, y: 1.5 }, { x: 2, y: 9 }, { x: 5, y: 0.3}],
{ stroke: "green" });

You can change the colors by using the setTheme() function while defining your chart.
Must look like :
require(["dojox/charting/Chart", "dojox/charting/themes/Shrooms", "dojox/charting/plot2d/Areas", ...],
function(Chart, Shrooms, Areas, ...){
new Chart(node)
addPlot("default", { type: Areas, tension: "X" })
setTheme(Shrooms)
addSeries("Series A", [1, 2, 0.5, 1.5, 1, 2.8, 0.4])
addSeries("Series B", [2.6, 1.8, 2, 1, 1.4, 0.7, 2])
addSeries("Series C", [6.3, 1.8, 3, 0.5, 4.4, 2.7, 2])
render();
});
In this example the Theme "Shrooms" will be loaded.
Here you can see, what themes are available for Charts:
http://demos.dojotoolkit.org/demos/chartTypes/demo.html
and in the dojo API you can find them under dojox/charting/themes.
Here's a good tutorial how you can define themes by yourself:

Echarts draw a circle with dashed border on the geo map

I don't know how to convert the unit of the cirle radius, now it's meters but I need to convert it into pixel.
I also want to know how to make the border of the circle become dashed border, like the picture (the circle with the white dashed border)
Here is the code.
const map_data = [];
const current_map_data = [];
this.current_map = this.$echarts.init(document.getElementById('map_id'));
this.$echarts.registerMap('my_map', map_data);
const typhoon_points = [
{name: 0, value: [124.36, 23, 6]},
{name: 1, value: [122, 23.8, 6]},
{name: 2, value: [120, 24.4, 6]},
{name: 3, value: [118.5, 24.8, 6]},
{name: 4, value: [117.2, 25.5, 6]}
];
const typhoon_lines = [
{"point": [0, 1], "coords": [[124.36,23], [122, 23.8]]},
{"point": [1, 2], "coords": [[122, 23.8], [120, 24.4]]},
{"point": [2, 3], "coords": [[120, 24.4], [118.5, 24.8]]},
{"point": [3, 4], "coords": [[118.5, 24.8], [117.2,25.5]]},
];
const option = {
geo: [{
map: map_name,
roam: 'move',
boundingCoords:[ [118, 26.5], [122.4,21.5] ],
center: center,
layoutCenter: ['50%', '50%'],
aspectScale: 1,
scaleLimit: { min: 1.6, max: 12.0 },
left: '0%',
zoom: zoom,
itemStyle: {
areaColor: 'none',
borderColor : '#999',
borderWidth: 1,
emphasis: {
areaColor: 'inherit',
},
},
}],
series: [{
selectedMode: false,
name: 'current_map',
type: 'map',
geoIndex: 0,
data: current_map_data,
zlevel: 3
}, {
name: "",
type: "lines",
zlevel: 6,
lineStyle: {
type: 'solid',
width: 1,
opacity: 1,
curveness: 0,
orient: 'horizontal',
color: "#000",
},
data: typhoon_lines,
}, {
name: '',
type: 'scatter',
coordinateSystem: 'geo',
color: ['#000'],
itemStyle: {
borderType: 'dashed', // it's not working
borderWidth: 50, // The unit of the symbol size is pixel, I need to convert it into pixel.
borderColor: 'green',
color: '#000',
},
data: typhoon_points,
}],
};
I created a line & circle layer into series, but I don't know how to change the border style and the unit of the symbol size (I think it's the radius of the circle)

Trying to update high chart data

I am trying to update the data series on the update button by providing new series. As the result, new series will be a plotting along with the old series.
And After plotting the new series, the values on are X-axis is clear up. Here I Am attaching the code snippet please have look.
Initial State config:
this.state = {
chartOptions: {
credits: {
enabled: false,
},
chart: {
type: 'spline',
},
title: {
text: 'Chart',
},
plotOptions: {

marker: {
enabled: false,
},
},
},
xAxis: {
gridLineWidth: 1,
type: 'datetime',
lineColor: '#999',
lineWidth: 1,
title: {
text: 'Time',
style: {
color: '#000',
},
},
},
yAxis: [
{
title: {
text: 'Value',
},
gridLineWidth: 1,
lineWidth: 1,
opposite: true,
plotLines: [
{
color: '#55c2ea',
width: 2,
value: props.data[0][1], // Need to set this probably as a var.
label: {
text: props.data[0][1],
textAlign: 'left',
verticalAlign: 'middle',
style: {
color: '#55c2ea',
fontSize: 16,
borderWidth: 1,
backgroundColor: '#55c2ea',
borderColor: '#55c2ea',
},
x: 330,
},
},
],
accessibility: {
enabled: true,
},
opposite: true,
},
],
time: {
useUTC: false
},
series: [
{
showInLegend: false,
color: '#FF0000',
data: props.data.slice(0, props.tradingInterval),
},
],
}
};
Update Function:
updateSeries = () => {
this.setState({ chartOptions: {
series: [
{
showInLegend: false,
color: '#FF0000',
data: this.props.data.slice(0, 15),}
]
} })
}
Graph Render code:
render() {
return (
<View style={styles.container}>
<HighchartsReactNative
styles={styles.chart}
options={this.state.chartOptions}
/>
<Button
title="Refresh"
onPress={this.updateSeries.bind(this)}/>
</View>
);
}
After updating graph looks like
Class Component Code: https://gist.github.com/cupatil/da00b0ab0866e3a4f9306f0425e92582
Also tried this code using a functional component.
Using Functional Component Code: https://gist.github.com/cupatil/2fc1862f64f3a511158ced3c6b64d215
But the same thing happens series changed but not able to plot the graph property as per the image. Also, X-Axis data not calculated properly.
Sample Series data that I am using:
[ { x: 1607883000000, y: 1.6093 },{ x: 1607882940000, y: 1.6094 },{ x: 1607882880000, y: 1.6093 },{ x: 1607882820000, y: 1.6094 },{ x: 1607882760000, y: 1.6094 },{ x: 1607882700000, y: 1.6094 },{ x: 1607882640000, y: 1.6095 },{ x: 1607882580000, y: 1.6094 },{ x: 1607882520000, y: 1.6095 },{ x: 1607882460000, y: 1.6093 },{ x: 1607882400000, y: 1.6095 },{ x: 1607882340000, y: 1.6095 },{ x: 1607882280000, y: 1.6088 },{ x: 1607882220000, y: 1.6096 },{ x: 1607882160000, y: 1.6095 },{ x: 1607882100000, y: 1.6096 },{ x: 1607882040000, y: 1.6096 },{ x: 1607881980000, y: 1.6096 },{ x: 1607881920000, y: 1.6097 },{ x: 1607881860000, y: 1.6097 },{ x: 1607881800000, y: 1.6099 },{ x: 1607881740000, y: 1.6101 },{ x: 1607881680000, y: 1.61 },{ x: 1607881620000, y: 1.61 },{ x: 1607881560000, y: 1.6099 },{ x: 1607881500000, y: 1.6099 },{ x: 1607881440000, y: 1.6099 },{ x: 1607881380000, y: 1.6098 },{ x: 1607881320000, y: 1.6099 },{ x: 1607881260000, y: 1.6098 },{ x: 1607881200000, y: 1.6098 },{ x: 1607881140000, y: 1.6098 },{ x: 1607881080000, y: 1.6099 },{ x: 1607881020000, y: 1.6098 },{ x: 1607880960000, y: 1.6099 },{ x: 1607880900000, y: 1.6098 },{ x: 1607880840000, y: 1.6098 },{ x: 1607880780000, y: 1.6099 },{ x: 1607880720000, y: 1.6098 },{ x: 1607880660000, y: 1.6096 },{ x: 1607880600000, y: 1.6097 },{ x: 1607880540000, y: 1.61 },{ x: 1607880480000, y: 1.6099 },{ x: 1607880420000, y: 1.6101 },{ x: 1607880360000, y: 1.61 },{ x: 1607880300000, y: 1.6101 },{ x: 1607880240000, y: 1.61 },{ x: 1607880180000, y: 1.6101 },{ x: 1607880120000, y: 1.6101 },{ x: 1607880060000, y: 1.61 },{ x: 1607880000000, y: 1.6099 },{ x: 1607879940000, y: 1.6099 },{ x: 1607879880000, y: 1.6098 },{ x: 1607879820000, y: 1.61 },{ x: 1607879760000, y: 1.6097 },{ x: 1607879700000, y: 1.6098 },{ x: 1607879640000, y: 1.6096 },{ x: 1607879580000, y: 1.6096 },{ x: 1607879520000, y: 1.6097 },{ x: 1607879460000, y: 1.6096 },{ x: 1607879400000, y: 1.6095 } ]
All right, I was doing it the other way around, and that's why I was not able to reproduce the described error. Well, so now I see the problem, but as I thought, it's caused by passing not sorted (x ascending order) data, what you can notice after opening the browsers console, and see the Highcharts #15 error.
In order to make it work correctly, you need to always make sure that you're passing the data, which is sorted in ascending order (point x values are increasing along with the array element index).
So, to sum up, sort the array:
[
// data here
].sort((a, b) => a.x - b.x)
then change the the way you prepare (slice) the initial data:
data.slice(data.length - 1 - 15, data.length - 1)
and now it should work as expected.

Place point over boxplot using plotlyjs and vue

I'm trying to place point over boxplot, however my attempt results in the point placed next to the boxplot:
data: [
{
x: [1, 2, 3, 4, 4, 4, 8, 9, 10],
type: "box",
name: "Set 1"
},
{
x: [5],
name: 'My special marker',
text: 'Some really interesting hover info',
marker: {
size: 5
}
},
],
layout: {
title: 'Revenues',
font:{
size:10
},
margin: {
l: 0,
r: 0,
b: 15,
t: 25,
pad: 0
},
height: 90,
dragmode: "pan"
},
Is it possible to place that point over boxplot using vue-plotly library?
Here I recreted the issue:
https://codesandbox.io/s/vue-plotly-delsw?file=/src/App.vue
EDIT:
For the desired result I need that addiotional point to be on top of the chart like this:
One solution is to set the size of the point's marker and the width of the bar such that they overlap each other. For example:
data: [
{
x: [1, 2, 3, 4, 4, 4, 8, 9, 10],
type: "box",
name: "Set 1",
width: 30,
},
{
x: [5],
name: "My special marker",
text: "Some really interesting hover info",
marker: {
size: 30
}
}
],

Can Dojo MouseIndicator be HTML and not just plain text?

Ive got some chart code whereas I add a MouseIndicator to a line chart. I want the text on the MouseIndicator to be HTML and I am not sure if this is possible since it is not working. Ive added a labelFunc to return the HTML I want, but it only ever shows up as plain text.
Ive got the code on JSFiddle (and below) so you can try it out.
Any help is appreciated.

By default only plain text is rendered because the rendering is either done by SVG or Canvas (or VML for old IEs). However you should be able to customize this to render some HTML.
The way to proceed is to tell the data indicator to not render the labels itself (labels: false) and do it yourself in when a change event occurs. Something like the following (here using a dijit/Tooltip but you can use any other way to render HTML):
require(["dojo/ready", "dojo/on", "dojox/charting/Chart", "dojox/charting/axis2d/Default", "dojox/charting/plot2d/Lines",
"dojox/charting/action2d/MouseIndicator", "dijit/Tooltip", "dijit/place"],

how to overlay a line on a dojo column chart

I am using a dojo column chart. I want to add a custom line (some kind of a threshold line) that is drawn on the plot.
So, lets say y axis ranges from 0 to 5. I want a horizontal line at, lets say, 4.2 running across the plot.
It is a column chart.
I was hoping to find some drawing APIs that can help me do custom drawing on the plot but i am unable to figure out how. I know the chart uses gfx and surface so if i can get a handle to the chart/plot surface perhaps i can draw a custom line? Will also need data to rendered co-ordinates mapping to make this happen
My current chart uses code like:
var mychart = new dojox.charting.Chart2D("columns").
addAxis("x", {fixLower: "minor", fixUpper: "minor", natural: true,
font: "normal normal 10pt Arial",
labels: [{value: 1, text: "Q2 FY11"},
{value: 2, text: "Q3 FY11"},
{value: 3, text: "Q4 FY11"},
{value: 4, text: "Q1 FY12"}]
}).
addAxis("y", {vertical: true, includeZero: false, fixLower: "major", fixUpper: "major", min: 0, max: 5, font: "normal normal 10pt Arial", majorTick: {color: "black", length: 6}, minorTicks: false}).
addPlot("default", {type: "ClusteredColumns", tension: "S", shadows: {dx: 2, dy: 2}, gap: 5, minBarSize : 14, maxBarSize:24, animate: { duration: 1000, easing: dojo.fx.easing.linear} }).
addSeries("Series A", [{ y: 2.3, tooltip: "FFFF"}, { y: 3.5, tooltip: "GGGG"}]).
addSeries("Series B", [1.2, 2.5]);
You could render the line using another plot.
new dojox.charting.Chart2D("columns").
addAxis("x", {fixLower: "minor", fixUpper: "minor", natural: true,
font: "normal normal 10pt Arial",
labels: [{value: 1, text: "Q2 FY11"},
{value: 2, text: "Q3 FY11"},
{value: 3, text: "Q4 FY11"},
{value: 4, text: "Q1 FY12"}]
}).
addAxis("y", {vertical: true, includeZero: false, fixLower: "major", fixUpper: "major", min: 0, max: 5, font: "normal normal 10pt Arial", majorTick: {color: "black", length: 6}, minorTicks: false}).
addPlot("default", {type: "ClusteredColumns", tension: "S", shadows: {dx: 2, dy: 2}, gap: 5, minBarSize : 14, maxBarSize:24, animate: { duration: 1000, easing: dojo.fx.easing.linear} }).
addSeries("Series A", [{ y: 2.3, tooltip: "FFFF"}, { y: 3.5, tooltip: "GGGG"}]).
addSeries("Series B", [1.2, 2.5]).
addPlot("threshold", { type: "Lines" }).
addSeries("threshold", [{x: 0, y: 4.2}, {x: 4, y: 4.2}], { plot: "threshold" }).
render();
Another simple example representing max_temperature as Lines and Min_temperature as Columns in the same chart:
var chart = new Chart("chartNode");
chart.addPlot("tempMaxPlot", {
type: "Lines",
markers: false
});
chart.addPlot("tempMinPlot", {
type: "Columns",
markers: true,
gap: 5
});
chart.addAxis("x");
chart.addAxis("y", { min: -3, max: 13, vertical: true, fixLower: "minor", fixUpper: "major" });
var chartData_tmax = [11,13,12,11,10,9,9,10];
chart.addSeries("tmax",chartData_tmax, { plot: "tempMaxPlot" });
var chartData_tmin = [1,1,2,1,0,-1,-1,0];
chart.addSeries("tmin",chartData_tmin, { plot: "tempMinPlot" });
chart.render();
Last but not least you can gfx drawing functions to draw a line manually, as described below:
