@elanchezhiyan,

To check the minimum or maximum value of the chart’s X-axis, you can use the axis get method. Please take a look at the code-snippet given below.

chart.axisX[0].get("minimum");
chart.axisX[0].get("maximum");

@edad_msft,

CanvasJS stockcharts plots all the chart elements on HTML5 canvas element, which is considered as an image by the narrator. Hence it’s not possible to have accessibility for input fields as of now. However, you can pass aria-label field to the entire chart to achieve accessibility. Please take a look at this JSFiddle for an example on the same.

Also, please refer to this forum thread for more information.

@elanchezhiyan,

In the JSFiddle that you have shared, you are not setting the X-axis minimum or maximum. Setting the minimum and maximum value for X-axis seems to be working fine for both date-time and numerical values.

If you are still facing issues, kindly update the JSFiddle with your use case and share it with us so that we can look into the code / chart-options being used, understand the scenario better and help you out.

@thefireescaper,

Can you kindly create JSFiddle reproducing the issue you are facing & share it with us so that we can look into the code / chart-options being used, understand the scenario better and help you out?

From what we have observed, sometimes things get delayed mostly when we are not able to reproduce the issue or not able to understand the exact scenario, or the solution that we provide may not work properly due to the variation in chart options being used by you and us.

Having a JSFiddle helps us in figuring out the issue and suggesting an appropriate solution accordingly.

@thefireescaper,

Glad that you were able to make it work. If you have any further queries or facing any other issues, kindly create a JSFiddle with your use case and share it with us so that we can look into the code / chart-options being used, understand the scenario better and help you out.

@elanchezhiyan,

You can scale-up or scale-down the chart before exporting using exportChart method and reset it back soon after exporting. Please refer to this forum thread for more information.

Please check this JSFiddle for a working example.

@thefireescaper,

You can use customBreaks for removing weekend gap from the chart. With the use of scale breaks, there are possibilities that the axis labels may appear at an unequal interval and they may overlap with each other. You can overcome this by using stripLines for labels.

Please take a look at this JSFiddle for an example on the same.

@thefireescaper,

You can try lazy loading the charts. We have tested the same using jquery.inview & it seems to perform better compared to the regular way of rendering charts / stockcharts.

Please check this JSFiddle for a working example.

@thefireescaper,

The memory for canvas buffer memory is limited to 25% of the RAM of the device. However, we have optimized memory consumption in CanvasJS v2.3.1 and v3.6. Kindly download the latest version of CanvasJS Charts from our download page.

@pfiasco,

The datapoint will be positioned exactly on the x and y coordinate that was passed. However, the size of the marker used to represent a particular datapoint can vary based on it’s size. For example: in your code, the last datapoint is { y: 50, x: 50 }, hence the center of the marker will be positioned on the coordinate { y: 50, x: 50 } and since you are setting axisX maximum to 50, only half the marker will be visible while the other half gets clipped. You will have to set axis maximum and minimum accordingly such that the entire datapoint can be accommodated within the plot area.

@pfiasco,

When axis minimum and maximum are set, the datapoints that are present either outside or nearer to the set range will get clipped. You can either decrease or increase the range to show datapoints without getting them clipped. In your case, setting maximum to 51 seems to be working fine. Please find the code snippet below.

axisX: {
  minimum: -1,
  maximum: 51
}

Please check this JSFiddle for a working example.

@lars_,

You can sort the datapoints before rendering the chart to achieve your requirement. Please refer to this forum thread for more information.

@elanchezhiyan,

All the elements of the chart and the size of the image is based on the number of pixels. DPI is a measurement of “Dots per Inch” however, images are measured in pixels. Please refer to this Stackoverflow thread for more information.

If you are looking to export charts at higher resolution, you can increase the size of the chart before exporting. Please take a look at this JSFiddle for an example.
