Scott,

a) Blank chart.
b) Using Ajax, get data and display on the chart.
c) Get more data from server as in b).

Please refer documentation on Live Updating Charts from JSON API & AJAX for step-to-step tutorial on rendering chart with data from server through AJAX call.

Allow data then to be zoomed.

Setting zoomEnabled property to true lets user zoom / pan the chart even in Live Charts.

Allow user to click on chart to create an event so I can see the position the user clicked at.

If you mean clicking on any dataPoint, please refer documentation on click event. Or if you like to click anywhere on the chart, you can bind click event to the chart-container and get to know the position of click. Please take a look at this JSFiddle which shows adding new dataPoint based on user clicked position.

@fbahashwan,

Do you mean JSON format of the data that you receive is in different format as [{months: “Jan”, total: 70},…]. If so, parsing it to the format accepted by CanvasJS before passing it to chart-options should work fine in your case. Please take a look at this JSFiddle.

If this doesn’t solve your requirement, kindly create sample project reproducing the issue you are facing, upload it to Google-Drive / Onedrive and share it with us so that we can run the project at our end, understand the scenario better and help you resolve it.

@gjoe,

Datapoint y-value can be a numeric. As you are storing it as a string in your JSON, parsing it to number before passing it to chart-options should work fine in this case y: Number(data[i].value__sum).

Please take a look at this JSFiddle.

@Balaji,

Trial Version is for evaluation purposes for 30 days which comes with ‘Trial Version’ watermark and ‘CanvasJS’ credit link. To use charts without ‘Trial Version’ and ‘CanvasJS’ Credit Link you will need to have a Commercial Version of CanvasJS. Please checkout License Page for more info & contact sales@canvasjs.com for sales related queries.

@y-hirano,

Datapoint gets enlarged when a dataPoint is highlighted (incase of scatter, line, bubble, etc). You can set highlightEnabled to false to disable highlighting of a dataPoint on hovering the mouse.

@devikagopakumar,

You can resize the chart by changing the height of the chart on resizing the panel as shown in this JSFiddle.

For faster response, fork out our template jsfiddle reproducing the issue you are facing. Having a jsfiddle helps us in figuring out the issue and many a times we can just edit your code on jsfiddle to fix the issue right-away. Please refer this thread for more info.

@navigatorus,

Please take a look at this JSFiddle which shows stripLine being updated and rendered at a static position in a dynamic chart.

Sven,

Datapoint x-value can either be numeric or date object, but you seems to be passing string – which is not supported. Either changing it to date-object or passing it as label should work fine in your case. Please take a look at this updated JSFiddle.

@navigatorus,

You can add as many striplines as you want by adding new object with value to stripLines array. Please refer documentation on stripLines for more info / customization options available.

Here is a code snippet that would help you add 3 stripLines over axisY:

stripLines: [{
    value: 3366500,
    label: "Average"
},{
    value: 7289000,
    label: "High"
},{
    value: 1613000,
    label: "Low"
}]

@karamsmbit-co-il,

You can achieve this by formatting the label displayed over axisY and content in toolTip according to your requirements with the help of labelFormatter and contentFormatter respectively, please refer documentation for more customization options. Please take a look at this JSFiddle.

@noesiscanvasjs,

There is no change in the API between v1.9.10 and v2.3.1 except change in theme and addition of new features in v2.0. Please refer this blog post for more info. Just replacing canvasjs.min.js should work fine.

Can you share the JSFiddle with your use-case & the chart-options that you are using so that we can look into it, understand it better and help you resolve the issue?
