@jamesrus52,

It seems to be working fine irrespective of chart-type. Can you kindly create JSFiddle reproducing the issue you are facing and share it with us so that we can look into your code, understand the scenario better and help you out?

@silemanbed,

Importing canvasjs.min.js file to the project as import * as CanvasJS from '/path-to-canvasjs-file/canvasjs.min' should work fine. Please take a look at this Sample Project.

If you are still facing the issue, please share sample project reproducing the issue you are facing over Google-Drive / Onedrive, so that we can run it locally at our end, understand the scenario better and help you out.

@joshl,

There is no restrictions on number of dataSeries, as of now.

@reena,

CanvasJS Chart just renders the data that’s being passed to chart-options. It seems like you are passing x-value(date) as label because of which there could be the mismatch of values. Passing date-time values as x-value, that’s read from the database, should work fine in this case.

@msingh,

CanvasJS supports exporting chart as an image or to print it. To export multiple charts rendered within a page, you can use html2canvas as shown in this JSFiddle, which can be integrated with JavaScript frameworks like Angular, React, etc.

Please refer this article for more info.

@reset,

I use a lot of data to create the graph, about 30,000 points, the problem is that if I have few points in the array (example 5,000) this is displayed correctly, but when I have many more it sends this error:

The issue is happening due to the incorrect format of dataPoints being passed to the chart-options. Removing redundant numbers between the objects of dataPoints array should work fine in this case. Please take a look at this Updated JSFiddle.

Format of dataPoints that you have passed:
dataPoints: [{"y": 24},{"y": 24},34,{"y": -315}]

Valid Format:
dataPoints: [{"y": 24},{"y": 24},{"y": 34},{"y": -315}]

other peculiarity, if I use the php function in example to create random data the graph is displayed.

$ i, “y” => $ y));
}
?>

if I use mine it only works with a few points

This is working fine as the format of dataPoints being generated is proper.

@ayanghatak,

A logarithmic axis can only plot positive values. There simply is no way to put negative values or zero on a logarithmic axis.

Fundamental: If 10^L = Z, then L is the logarithm (base 10) of Z. If L is a negative value, then Z is a positive fraction less than 1.0. If L is zero, then Z equals 1.0. If L is greater than 0, then Z is greater than 1.0. Note that there no value of L will result in a value of Z that is zero or negative. Logarithms are simply not defined for zero or negative numbers.

Tejal,

Y-Value in toolTip is not being displayed for the value 0.2 due to yValueFormatString that you have set. Setting yValueFormatString: "$#,##0.#k" should work fine in this case. Please refer documentation for more formatting options available.

@kalev-noor,

Syncing crosshair across charts is not possible using internal properties, as of now. However the work-around provided is one of the solution that seems to work fine irrespective of number of charts. Please feel free to share any other solution / suggestions to do the same.

@naimed,

Sorry, sharing chart via Facebook / Twitter is not available as of now. However you can get base64 image of the chart using toDataURL and share it via Facebook / Twitter. Please take a look at this article on Posting HTML5 Canvas Image to Facebook & Twitter for tutorial and code-snippet for the same.
