@snehal,

I want the labels should come from database and it should plot the graph, according to that particular labels should display the status in the graph,

In multiseries charts, data-points are grouped based on common x-values. Providing same x-values along with labels should work fine in your case.

The sample code provided in the previous reply seems to be working fine as per your requirements. If there are any changes in the code / database, please share the updated code that reproduces the issue you are facing, so that I can look into it and help you resolving it.

@robertlight,

You can programmatically zoom / pan to a region by setting viewportMinimum and viewportMaximum. In your case, you can set viewportMaximum to null (which resets the viewportMaximum) when user has zoomed / panned towards the latest dataPoint (latest part of the chart) using rangeChanged event. Please take a look at this JSFiddle.

@elcollie,

Thanks for reporting the use-case. We will look into the issue and fix it in future versions.

To work-around this issue, you can set axis labelFontColor to “transparent” instead of using labelFormatter to hide the axis labels. Please take a look at this updated JSFiddle.

@wonky,

I went through the source code of the page that you have shared and observed that, within the showScript1757, showScript1758 and showScript1759 methods, you are instantiating new charts as chart_1757, chart_1758 and chart_1759 but calling render method as chart.render() and not chart_1757.render(). Calling render method on instantiated objects should work fine in your case, i.e changingchart.render(); to chart_1757.render();.

Eran,

question 2: how can I delete a marked stripline?

You can remove selected stripLine dynamically using remove method. Please take a look at this JSFiddle where stripLines are deleted dynamically on double clicking them.

question 3: please refer to the following image: https://imgur.com/XI0P34N
I am actually plotting a scatter graph with a lot of data: can I somehow assign a color to a point depending on the number of occurences? Example: if I have 10 points which are equal (same x- & y-axis value), then plot the point yellow, if I have 20 points which are equal, plot the point blue etc.

You can set color to the dataPoint based on number of occurrences. Please refer this stackoverflow thread for more info on finding the number of occurrences of an element in an array of objects.

question 1: how can I drag and drop stripline boarders, meaning: I set them with the mouse, and then I want to move the boarders to the left/right

We are looking into this and will get back to you at the earliest.

@tejal,

Setting yValueFormatString to “#,###.00” formats y-values in toolTip and indexLabel show only 2 decimal values. Please take a look at this updated JSFiddle.

@paulfansare,

The method that calculates the minimum, maximum and other parameters is called only on rangeChanged event because of which table is populated only when you zoom/pan or reset the chart. To populate the table soon after rendering the chart, you need to call the method soon after chart.render().

chart.render();
showTableData(chart);

Please take a look at this Updated JSFiddle.

@paulfansare,

The link that you have shared seems to be working fine.

The JSFiddle that was shared earlier was adding 3 rows to the table which can be made generic to add number of rows based on number of dataSeries as shown in this updated JSFiddle.

@mhdajmalik,

Chart should look same when same options and dataPoints are passed, I don’t understand why it looks different in your case. Could you please create JSFiddle reproducing the issue so that I can look into it and resolve it.

Sateesh

Please take a look at our jQuery Gallery for an example on Chart inside resizable container. You can also make it draggable as shown in this JSFiddle.

Please share code to my mail id which is mentioned below.

We don’t provide email-based support however please refer the links shared above, which includes source code.

@paulfansare,

You can update chart options dynamically. Please take a look at documentation on Updating Chart Options and Data for the same.

In your case, you can just update dataPoints of same dataSeries rather than removing dataSeries and adding new one. Please take a look at this JSFiddle.

@daringdan,

If the length of video (in seconds / milliseconds) matches with the range of axisX (in seconds / milliseconds), you can seek video based on clicked position – with the help of convertPixelToValue method. Please take a look at this JSFiddle.

@snehal,

You can read data from database and parse it according to your requirements. Please take a look at this sample project where stacked-column chart is rendered by accepting regDate and function fields from database. You can further customize it to read any field based on your requirements and render chart.

Also refer this forum thread for more info on rendering chart in PHP with data from database.

@paulfansare,

It would be helpful for us to understand your issue better if we could run the code locally at our end and try out the scenario you are talking about, but the code that you have shared is partial, which we can’t make it work at our end. So I request you to create sample project reproducing the issue you are facing along with sample data and share it with us over Google-Drive or Onedrive.
