For all the different plotly languages version there is an option to generate graphs with two Y axis.
Either with the use of secondary_y or yaxis2 depending on the language.
I have browsed the different examples on the Plotly.kt github but haven't found a way to do this.
Is this even possible with the Kotlin version of Plotly ?
I have tried adding two yaxis blocks, but the second one just seems to overwrite the first one.
val plot = Plotly.plot {
traces(
scatter {
x.strings = priceData.map { it.first.toString() }
y.numbers = priceData.map { it.second }
mode = ScatterMode.lines
axis("Price")
},
bar {
x.strings = volumeData.map { it.first.toString() }
y.numbers = volumeData.map { it.second }
marker {
width = 1.0
opacity = 0.4
}
axis("Volume")
}
)
layout {
title { text = "Sales"}
showlegend = false
xaxis {
type = AxisType.date
gridwidth = 2.0
}
yaxis {
type = AxisType.linear
automargin = true
gridwidth = 2.0
title = "Price"
}
yaxis {
type = AxisType.linear
showgrid = false
title = "Volume"
}
}
}

I'm created custom dialog from common class in ini
init {
activity.setContent {
CustomDialog(viewModel)
}
}
#Composable
fun CustomDialog(viewModel: ViewModel){
Dialog(
onDismissRequest = { },
properties = DialogProperties(dismissOnBackPress = true, dismissOnClickOutside = true)
) {
}
}
But under dialog background is an empty activity, but must be a preference activity.
Not correct composable:
correct dialog via XML:
I tried, but didn't help
Surface(modifier = Modifier.background(Color.Transparent)) {
CustomDialog(viewModel)
}
```
Exampe:
Dialog(onDismissRequest = { onDismissRequest() }, properties = DialogProperties()) {
Column(
modifier = Modifier
.wrapContentSize()
.background(
color = MaterialTheme.colors.surface,
shape = RoundedCornerShape(size = 16.dp)
).clip(shape = RoundedCornerShape(size = 16.dp))
) {
//.....
}
}
Found solution:
dialog?.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
dialog?.window?.setDimAmount(0.0f)
I am developing a little application in compose for desktop on my windows machine. I put a OutlinedTextField into a column, which is in row. The problem is, that I cant see any text within it. Neither the default, nor am I able to edit the text. The box is focusable, but not editable.
I discovered, that the row is drawn above of my column. I assume that the row is swallow the event, or overpaint the text. I tried to set the z-index to high, but it didn't have any effect.
#Composable
fun menuInLeftSplitContent() = Row(Modifier.padding(all 5.dp).zIndex(-1F).background(Color
.Black)) {
Column {
IconButton(modifier = Modifier.padding(end = 5.dp), onClick = {}) {
Icon(Icons.Rounded.Add, "Add")
}
}
Column(modifier = Modifier.zIndex(20F)) {
val mutableText = mutableStateOf("Hello World")
OutlinedTextField(
value = mutableText.value,
onValueChange = { },
modifier = Modifier.fillMaxSize(),
singleLine = true,
leadingIcon = { Icons.Filled.Search },
enabled = true,
keyboardOptions = KeyboardOptions(
capitalization = KeyboardCapitalization.Characters,
autoCorrect = false,
keyboardType = KeyboardType.Text,
imeAction = ImeAction.None
),
maxLines = 1,
readOnly = false
)
}}
If the column wasn't overpainted by the row, you would see the picture beneath.
This is how it should look like.
I faced the following problem - items of the dropdown are not the same width as OutlinedTextField
Looked for the solution - found the following:
Add the variable to keep textField width:
var textFieldSize by remember { mutableStateOf(Size.Zero) }
Set the value in the onGloballyPositioned of TextField
onGloballyPositioned { coordinates ->
textFieldSize = coordinates.size.toSize()
}
Read the value in ExposedDropdownMenu
ExposedDropdownMenu(
expanded = expanded,
onDismissRequest = { expanded = false },
modifier = Modifier
.background(Color.White)
.width(with(LocalDensity.current) { textFieldSize.width.toDp() })
)
The problem is that it works fine with DropdownMenu, but doesn't work with ExposedDropdownMenu. What's the problem?
Here's the full code:
var expanded by remember { mutableStateOf(false) }
val sexList by remember { mutableStateOf(listOf("Male", "Female")) }
var textFieldSize by remember { mutableStateOf(Size.Zero) }
val icon = if (expanded)
Icons.Filled.ArrowDropUp
else
Icons.Filled.ArrowDropDown
ExposedDropdownMenuBox(
modifier = modifier
.clickable(onClick = { expanded = true }),
expanded = expanded,
onExpandedChange = { expanded = !expanded }
) {
OutlinedTextField(
value = "",
onValueChange = {},
modifier = Modifier
.fillMaxWidth()
.onGloballyPositioned { coordinates ->
textFieldSize = coordinates.size.toSize()
},
colors = TextFieldDefaults.textFieldColors(
backgroundColor = BorderColor,
unfocusedIndicatorColor = Color.Transparent,
focusedIndicatorColor = BrandColor,
focusedLabelColor = BrandColor,
),
leadingIcon = {
Image(
painter = painterResource(id = R.drawable.ic_complete_registration_sex),
contentDescription = null
)
},
trailingIcon = { Icon(icon, null) },
shape = RoundedCornerShape(Dimen.Dimen14),
label = {
Text(
"Choose Gender",
style = PoppinsNormalStyle14
)
},
readOnly = true
)
ExposedDropdownMenu(
expanded = expanded,
onDismissRequest = { expanded = false },
modifier = Modifier
.background(Color.White)
.width(with(LocalDensity.current) { textFieldSize.width.toDp() })
) {
sexList.forEach {
DropdownMenuItem(
onClick = { expanded = false },
) {
Text(it, style = PoppinsNormalStyle12Gray2)
}
}
}
}
ExposedDropdownMenuBox is built to calculate width for you so you don't have to use all this onGloballyPositioned related logic.
The fact that it doesn't work is a known issue.
Until it's fixed it's recommended to use DropdownMenu with Modifier.exposedDropdownSize()(this modifier will apply the width calculated by ExposedDropdownMenuBox) instead of ExposedDropdownMenu:
DropdownMenu(
expanded = expanded,
onDismissRequest = { expanded = false },
modifier = Modifier
.background(Color.White)
.exposedDropdownSize()
) {
sexList.forEach {
DropdownMenuItem(
onClick = { expanded = false },
) {
Text(it, style = PoppinsNormalStyle12Gray2)
}
}
}
I am using xy chart in amcharts as per my requirement.
In that amcharts, whenever on click of a bubble, I need to highlight the bubbles. So I have added listeners to my options as follows:
"listeners": [
{
"event": "clickGraphItem",
"method": function(event) {
var bubbleId = event.item.dataContext.id;
var toolTip = "";
dataProvider.forEach((data) => {
if (bubbleId != "" && bubbleId == data.id) {
if (data.bubbleSize == 10) {
data.bubbleSize = 20;
data.shape = "diamond";
} else {
data.bubbleSize = 10;
data.shape = "round";
}
} else {
data.bubbleSize = 10;
data.shape = "round";
}
});
this.AmCharts.updateChart(this.chart, () => {
// Change whatever properties you want
this.chart.dataProvider = dataProvider;
});
}
}],
But I am getting an error as "Cannot read property 'Amcharts' of undefined". I am not able to resolve the issue. Can anyone help me on this?
Referal Code for Amcharts angular as follows:

I'm a beginner in VueJS. And as part of my learning process, I'm building a knob for my Pomodoro app. This is my fiddle.
I copied the knob code from codepen, which is implemented using jquery. As you can see in the fiddle most of the job is done by jquery.
I need to try and do this using Vue.js, using its methods and states.
How to refactor this code to a better Vue.JS code? Any suggestions much appreciated.
Vue.component('timer', {
mounted() {
var knob = $('.knob');
var angle = 0;
var minangle = 0;
var maxangle = 270;
var xDirection = "";
var yDirection = "";
var oldX = 0;
var oldY = 0;
function moveKnob(direction) {
if(direction == 'up') {
if((angle + 2) <= maxangle) {
angle = angle + 2;
setAngle();
}
}
else if(direction == 'down') {
if((angle - 2) >= minangle) {
angle = angle - 2;
setAngle();
}
}
}
function setAngle() {
// rotate knob
knob.css({
'-moz-transform':'rotate('+angle+'deg)',
'-webkit-transform':'rotate('+angle+'deg)',
'-o-transform':'rotate('+angle+'deg)',
'-ms-transform':'rotate('+angle+'deg)',
'transform':'rotate('+angle+'deg)'
});
// highlight ticks
var activeTicks = (Math.round(angle / 10) + 1);
$('.tick').removeClass('activetick');
$('.tick').slice(0,activeTicks).addClass('activetick');
// update % value in text
var pc = Math.round((angle/270)*100);
$('.current-value').text(pc+'%');
}
var RAD2DEG = 180 / Math.PI;
knob.centerX = knob.offset().left + knob.width()/2;
knob.centerY = knob.offset().top + knob.height()/2;
var offset, dragging=false;
knob.mousedown(function(e) {
dragging = true;
offset = Math.atan2(knob.centerY - e.pageY, e.pageX - knob.centerX);
})
$(document).mouseup(function() {
dragging = false
})
$(document).mousemove(function(e) {
if (dragging) {
if (oldX < e.pageX) {
xDirection = "right";
} else {
xDirection = "left";
}
oldX = e.pageX;
if(xDirection === "left") {
moveKnob('down');
} else {
moveKnob('up');
}
return false;
}
})
}
});
This example runs without jQuery.

Declare all the variables you need in the data function.
Declare all functions under the methods property.
Declare variables that are derived from other variables in the computed property, such as knobStyle, activeTicks, and currentValue, which are all computed from angle. Whenever angle changes, these 3 computed properties will automatically update.
Regarding the general usage of Vue, you should focus on manipulating the data, and letting Vue update the DOM for you.
