Good Day To All
I'm new to pCharts, works great!
I'm trying to create a bar chart with 2 thresholds and display different bar colors. Setting the thresholds is done and works well. Now I would like to set the standard palette to a set color and only the bars that exceed the specified second threshold should be a different color.
My data consists of times file were imported
So in theory, if possible, all bars exceeding the 2nd limit should be red or pink or whatever.
Is this possible? If so, where do I start fiddling?
I have tried OverideColors with an if statement but it seems not to work so well.
Any info would be very helpful.
Thanks
Ok, so here is the code. I know there might be better or cleaner ways of doing it but this works:
/*Palette per Bar*/
$thold = strtotime("09:30:00");
foreach ($lastdate as $over) {
if ($over < $thold) {
$color = array("R"=>0,"G"=>204,"B"=>204);
$Palette[] = $color;
}
else {
$color2 = array("R"=>224,"G"=>46,"B"=>117);
$Palette[] = $color2;
}
}
Hope this helps

I am trying to write a pine script with two indicators one overlaid on the chart (EMA) and another on its own?(Stoch) I cannot seem to find any info on how to separate these (Visually) but keep them within 1 pine script, ie to be able to take trading decisions based on these.
The earlier answer from Luc is right, unfortunately. Each script can either create plots that are overlaid on the default price chart, or shown in a different pane, but not both. But there is a workaround.
Suppose you've made some non-trivial calculation in your script and you'd like to put it in different pane. E.g. the next code:
//#version=4
study(title="Stochastic", shorttitle="Stoch", format=format.price, precision=2)
periodK = input(14, title="K", minval=1)
periodD = input(3, title="D", minval=1)
smoothK = input(3, title="Smooth", minval=1)
k = sma(stoch(close, high, low, periodK), smoothK)
d = sma(k, periodD)
plot(k, title="%K", color=color.blue)
plot(d, title="%D", color=color.orange)
h0 = hline(80)
h1 = hline(20)
fill(h0, h1, color=color.purple, transp=75)
// This next plot would work best in a separate pane
someNonTrivialCalculatedSeries = close
plot(ema(someNonTrivialCalculatedSeries, 25), title="Exporting Plot")
Because they have different scale, one of them most likely will break another indicator's scale.
So you'd like show Stoch in different pine, whereas ema() should be overlayed with the main chart. For that you should make the next steps:
Turn off in the study's the extra plot to return scale to normal:
Apply to the chart the next script:
//#version=4
study("NonOverlayIndicator", overlay=true)
src = input(defval=close, type=input.source)
plot(src)
Choose in the second's script inputs source required plot from the first script:
And voilà - you got the plots in different pines:
But if you want split the plots because you have retrictions on amount of studies you allowed to apply (e.g. 3 for free-account) - that won't help you.
It cannot be done. A script runs either in overlay=true mode on the chart, in which case it cannot direct plots elsewhere, or in a separate pane when overlay=false (the default).
When the script is running in a pane, it can change the color of the chart bars using barcolor(), but that's the only way it can modify the chart.
It is possible to rescale signals so that multiple bounded (e.g., 0-100, -1 to +1) signals generated by one script appear one on top of the other, but this is typically impossible in overlay mode, as the vertical scale varies with the bars on the chart. The only way for an overlay script to work with its own scale is when it uses No scale, but this prevents the indicator's plots to plot relative to price, and so the chart's bars.
Nice workaround from Michael.
Unfortunately, this only seems to work to pass data for one plot.
I would like to pass data for 3 different plots to the stock price graph.
If I try this, for 'input.source' I can only select the standard sources: "open, high, low, close ...". I can not select the data from other indicators.
If I remove plots 2 and 3, it works as Michael described.
Anybody has a workaround for the workaround..? ;-)
My colleague and I am designing a survey using Qualtrics. On one page respondents must move a series of sliders.
We need to display the output of a function of the values of the sliders on the same page, ideally also in the form of another slider.
All of this must be done while the respondent moves the sliders.
Concretely, suppose the following:
value of slider 1 = 30;
value of slider 2 = 10;
value of slider 3 = 0
Output to be displayed = 30 x 20 + 10 x 5 + 0 x 15 = 650
where the 20, 5 and 15 are just arbitrary constants in the background.
If the user were to move slider 1 to 31, the displayed output should automatically update in real time to 670.
Any tip on how this is done? We're newbies to qualtrics and completely inexperienced with Java, so we'd be very grateful to anyone willing to provide us with working code. Thanks!
An update on my question, and a clarification after a comment received.
We were of course not asking for someone else to do our job. Just for a pointer in the right direction.
Based on an answer to a different question, I've managed to put this javascript together. It works, which is encouraging..
Code follows.
Qualtrics.SurveyEngine.addOnReady(function()
{
/*Place your JavaScript here to run when the page is fully displayed*/
var that=this.questionId;
jQuery("<p style='width:100%'><br><strong> Output <span id='OUT'>0</span></strong>").insertAfter("table.sliderGrid");
jQuery(document).on('change', function(){
var firstslider=parseInt(jQuery("[id='"+that+"~1~result']").val());
var secondslider=parseInt(jQuery("[id='"+that+"~2~result']").val());
var N=firstlider+secondslider*2;
jQuery("#OUT").text(N);
});
I am now using the MPAndroidChart to draw line chartmy chart
As you can see from the above screenshot, the color specified by me(showed in legend) is not the same as the finally filled in below the chart, is there any way to make sure that the different color will not mixed together?
Below is the code I used to draw two of the lines
LineDataSet vlfDs = new LineDataSet(vlfValues, "VLF");
vlfDs.setMode(LineDataSet.Mode.CUBIC_BEZIER);
vlfDs.setCubicIntensity(0.2f);
vlfDs.setDrawFilled(true);
vlfDs.setDrawCircles(false);
vlfDs.setLineWidth(0);
vlfDs.setCircleRadius(4f);
vlfDs.setColor(Color.YELLOW);
vlfDs.setFillColor(Color.YELLOW);
vlfDs.setFillAlpha(100);
LineDataSet lfDs = new LineDataSet(lfValues, "LF");
lfDs.setCubicIntensity(0.2f);
lfDs.setDrawFilled(true);
lfDs.setDrawCircles(false);
lfDs.setLineWidth(0);
lfDs.setCircleRadius(4f);
lfDs.setCircleColor(Color.WHITE);
lfDs.setColor(Color.GREEN);
lfDs.setFillColor(Color.GREEN);
lfDs.setFillAlpha(100);
hrvLineData = new LineData(hfDs,lfDs,vlfDs, hrDs);
hrvLineData.setValueTextSize(0);
hrvLineData.setDrawValues(false);
hrvChartView.setData(hrvLineData);
hrvChartView.invalidate();
It's turned out that I need to use setFillAlpha(255) instead of setFillAlpha(100)
You can also use something similar to the following solution which overrides the default LineChartRenderer and a uses a custom implementation of IFillFormatter to fill only the areas between the datasets.

I have this interactive chart here. As its data change depending on selected time period I wish to set the date range from Nov-10 to Jul-14, no matter the data. I know that I must use overrideMax on x axis, but I can't make it to work. I guess it's a matter of date formatting. Every single combination I've tried gives the following as result.
What is the right formatting? Thanks a lot.
EDIT: Thank you very much on your quick response, John. Now it is working. I'm loving Dimple more and more!
I have another question regarding this chart. Is there any way to arrange drawing order of series? I would like 'Previsión' to be sent to back. Now it is drawn depending on time period.
EDIT 2: Based on this other question I think I figured out a solution. With a 50ms delay after the chart is drawn I simple erase the circles and paths I wish to be at the front and then append them to the chart svg object.
setTimeout(function () {
var datoCircles = svg.selectAll('circle[id*=Dato]:not([id*=futuro])');
var prevCircles = svg.selectAll('circle[id*=Prev]');
var prevPaths = svg.selectAll('path[class*=Prev]');
datoCircles.remove();
prevCircles.remove();
prevPaths.remove();
// Convertimos la seleción d3 a objetos jQuery
$(svg.selectAll('svg > g')[0])
.append($(prevPaths[0]))
.append($(prevCircles[0]))
.append($(datoCircles[0]));
}, 50);
They need to be set with JavaScript date objects, as native date parsing in JavaScript causes cross browser problems, I recommend using the d3 method:
x.overrideMax = d3.time.format("%Y-%m-%d").parse("2014-05-09");
With this approach you can use whichever date format suits you.
Does anyone have any experience with using a url to target a specific slide in a Soliloquy slider? I am using multiple sliders that I need to link to specific slides of from external pages/sites. The Soliloquy Docs provide this info (soliloquywp.com/docs/dynamically-set-the-starting-slide/) as closest to the solution but, for a php noob like me, the explanation is a bit terse and lacking, my fault, not theirs.
The example given in the docs seems to be a custom filter for a specific slide in a specific slider. I need to target slides in multiple sliders with urls. I guess I need help understanding the filter's function. I have commented out what I think each part does. Maybe someone could show me where I'm wrong?
//OP: I don't understand, what ids/slides are represented by the 10 and 2 values in these parameters. Where do I find these?
add_filter( 'soliloquy_pre_data', 'tgm_soliloquy_dynamic_starting_slide', 10, 2 );
function tgm_soliloquy_dynamic_starting_slide( $data, $slider_id ) {
// If the proper $_GET parameter is not set or is not the proper slider ID, do nothing.
//OP: Is the 'sol_slide' parameter for ALL soliloquy sliders in my site or is it the name in the Dashboard given when constructing the slider?
if ( empty( $_GET['sol_slide'] ) ) {
return $data;
}
// Change this if you want to target a specific slider ID, or remove altogether if you want this for all sliders.
//OP: I believe to target ALL sliders in my site I should comment this out. Right?
if ( 51064 !== $slider_id ) {
return $data;
}
// Set the slide number as a config property. Also preventing randomizing slides.
$data['config']['start'] = absint( $_GET['sol_slide'] );
$data['config']['random'] = 0;
// Optionally prevent autostarting the slider. Uncomment if you want that.
//$data['config']['auto'] = 0;
return $data;
}
Basically, I guess I am asking for a little help with implementing this filter to target any slide in any slider with a url. Slim odds, but I'm dead in the water! Big thanks to anyone who can shed some light on this for me.
Complete, correctly functioning answer is here provided the plugin author, of course, duh: http://soliloquywp.com/support/topic/a-way-to-link-directly-to-a-specific-slide/
The value "sol_slide" is generic to any slider created with the plugin. Just put the custom filter provided in the example into your, hopefully, child-theme's functions.php, and construct your urls targeting specific slides like so: http://mywebsite.com/specific-product-page-with-slider/?sol_slide=3. Slide numbering is based on zero so 1 = 2 etc. Works like a charm.
