Recently I changed Floats to FlexBox to have easier work with panels (as advised on other questions I did). While most of the things are working as I expect it, I'm having a problem with Apex Charts after the change.
Full code is here:
https://github.com/EvotecIT/PSWriteHTML/blob/master/Examples/Example12-Charts/Example12.html
Here's how it looks when loaded. You will notice that in 1st and 2nd-row charts go out of bounds even thou the panel they are in is in place and it works for the top row.
And if I do resize (like 1mm) it will start working correctly.
Any idea what could be the problem?
In apex charts CSS it has comments to not use overflow (I tried and it doesn't do anything) but to be honest, I even once forgot to attach that CSS and nothing changed (like everything is done by the JS.
.apexcharts-canvas {
position: relative;
user-select: none;
/* cannot give overflow: hidden as it will crop tooltips which overflow outside chart area */
}
/* scrollbar is not visible by default for the legend, hence forcing the visibility */
Keep in mind that I'm a total noob when it comes to JS/CSS/HTML so excuse my language.
You need to move all your scripts to the end instead of injecting in the HTML to allow the SVG Document parser to get the element's size correctly.

I draw a default OHLC chart. Then add a simple scatter series to it.
I set chart level config to share tooltips.
tooltip: { shared: true }.
But two series won't share tooltips at all.
Another big problem is that I cannot control the mouse hover effect on the new series. If you try the demo below, after clicking the AddSeries button at the bottom, the newly added series will be highlighted on mouse hover. I try to remove the mouse over effect and control it with the lineWidthPlus parameter, but there is no effect on the newly added series. Can anyone shed some light on this?
"hover": {
"enabled": false
},
https://jsfiddle.net/2t7fg9rc/
What do you think about adding the line series instead of scatter? I cannot see the hover issue that you described while using the line series.

I am making a simple bar graph in Highcharts and want all the columns of the graph blue except for one. I have found how to change the color on one column when the data in the data set is in an array by using {y:value, color:"color"} on the particular data point you want to change. However, my values are in CSV form and this technique doesn't work.
I have tried to use the technique used for an array, that is {y:value, color:"color"} in the data set in various ways to no avail. I am looking for the proper way to do this when the data is in CSV format.

In load event function you can use update method on a specific point and change the color:
chart: {
...,
events: {
load: function() {
var point = this.series[0].points[3];
point.update({
color: 'red'
});
}
}
}

I am making an AMcharts stockchart with markers on it. The way I have done the markers is by taking the value of the price series only if a condition is met. Therefore the data has 4 columns:
Date
SPY price (SP500 etf)
Daily RSI Stance 1 (1,0 boolean value)
Signal (If Daily RSI Stance 1 = 1, SPY price, else blank)
CSV with data found here:
http://quantresearch.club/wp-content/themes/oceanwp/testing/RSI1dip.csv
The problem is that even though the data is perfectly aligned it does not show that way on the amcharts chart, which has me completely stumped. The markers ie. "4. Signal" show up under the "2. SPY price" timeseries. As shown here:
and finally for the code:
This first part is contained in the larger code below and it is what makes both timeseries appear.

Thank you very much.
The issue is due to the stock chart's data grouping functionality. The chart groups data to improve performance when there a lot of points visible, which impacts how the line is drawn as it is using points derived from its data grouping algorithm. By default it's using the "Close" value in the grouping to plot your points and changing the periodValue in your SPY graph will change the appearance. Since your Signal data set has much fewer points in comparison, the chart simply plots out the raw values for that graph, which do not match up to your grouped SPY graph's values, regardless of which periodValue you use.
Your only option to make the values from both graphs line up correctly is to disable data grouping by setting maxSeries to 0 in your categoryAxesSettings. This will impact performance if you have a lot of points.
Here's a codepen of your chart with maxSeries set to 0.
We are trying to display three sets of data, two stacked, one unstacked using chart.js. We defined two sets of axis where only the stacked data shows and the unstacked data does not. We can only get the axis to display or not display, but we cannot get the data to appear at all.
We know the data is valid because we can get all of the data to stack together, but not separately.
recycleChartData = {
"type":"bar",
"data":{
"labels":["Mar-2016"],
"datasets":[
{
"label":"benchmark",
"backgroundColor":"#ff3300",
"yAxisID":"stacked_testY2",
"xAxisID":"stacked_testX2",
"data":["2632.29"]
},
{
"label":"Crossville",
"backgroundColor":"#009900",
"yAxisID":"stacked_testY",
"xAxisID":"stacked_testX",
"data":["2268.44"]
},
{
"label":"test",
"backgroundColor":"#ffff00",
"yAxisID":"stacked_testY",
"xAxisID":"stacked_testX",
"data":["181.92"]
}
]
},
"options":{
"scales":{
"yAxes":[
{
"id":"stacked_testY",
"position":"left",
"stacked":true,
"display":true
},
{
"id":"stacked_testY2",
"position":"left",
"stacked":false,
"display":false
}
],
"xAxes":[
{
"id":"stacked_testX",
"position":"bottom",
"stacked":true,
"display":true
},
{
"id":"stacked_testX2",
"position":"bottom",
"stacked":false,
"display":false
}
]
}
}
};
It's odd that your code doesn't work, if you change the non-stacked dataSet to a line graph you see the data! Maybe worth posting an issue on the chartjs github.
But...
There was a feature released in 2.5.0 which will allow for this sort of scenario. More on what it is can be read here, https://github.com/chartjs/Chart.js/issues/2643.
Basically, you can add a new property stack on each of your dataSets to denote which stack you would like it to go on to, so for example with your data you could remove the extra scales and have 2 stacks

},{

I came across this issue when trying to find out how to stack specific datasets of a line diagram in Chart.js v2.x.
Chart.js v3.x supports the stack attribute for line diagrams but in Chart.js v2.x:
you have to use multiple y-axis
to align the values you need to calculate the maximal value yourself and set ticks.max or ticks.suggestedMax in the axis configuration.
false console:
let yMax = 3000; // Calculate value beforehand.

It is a known bug in highcharts-ng caused by navigator. Reported here.
As a workaround you can define global animation in chart property.
