    You can import CanvasJS from angular-charts package to add custom colorset as shown in the code-snippet below.

    import { CanvasJS } from '@canvasjs/angular-charts';
    CanvasJS.addColorSet('customColorSet', ['#4661EE', '#EC5657', '#1BCDD1', '#8FAABB', '#B08BEB', '#3EA0DD', '#F5A52A', '#23BFAA', '#FAA586', '#EB8CC6']);

    Please take a look at this Stackblitz for an example of the same.

    in reply to: Bar Chart – label for each bar not visible #44679

    @kpandey017,

    Labels are displayed at regular intervals on the axis. Additionally, to enhance readability and prevent overlapping, the chart omits alternate labels, in some cases. However, if you prefer to display all labels, you can achieve this by setting the interval to 1.

    axisX: {
      interval: 1
    }

    Please take a look at this updated JSFiddle for the working code.

    @codetonight,

    You can update the chart title dynamically to reflect the name of the selected datapoint upon clicking. Please find the code-snippet below:

    click: function(e) {
      e.chart.title.set("text", e.dataPoint.name);
    }

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

    in reply to: Misaligned secondary axis ticks when hiding labels #44457

    @crapo,

    Bounds of axis depends on multiple factors including the axis labels. In your case, ticks of axisY & axisY2 are not getting aligned as labels are shown for axisY, which takes up space towards the top of the axis & axisY2 doesn’t. You can overcome this either by reducing labelFontSize in axisY or by setting labelFontColor of axisY2 to be same as chart-background along with a negative margin. Please take a look at this updated JSFiddle for an example where ticks are aligning.

    in reply to: canvasjs not working Nextjs Build #44448

    @itissandeep,

    We tried deploying the production build in a server and in vercel, it seems to work fine when you mention chart component to be used in client-side ("use-client"). Please take a look at this link for a working sample that’s deployed in vercel and checkout this Github repository for the project.

    If you are still facing issue, kindly share your project with us over Google-Drive or Onedrive (or in Github) so that we can try deploying it from our side to understand the scenario better and help you out.

    in reply to: canvasjs not working Nextjs Build #44444

    @itissandeep,

    CanvasJS is a client-side library and has to be prevented from rendering at server-side. When you try to generate build for production, it causes issue with libraries that depend on the browser’s window object. You can import CanvasJS package dynamically by passing ssr: false that disables importing of components that are not needed for SSR. Please take a look at this sample project for a working example on adding CanvasJS React Charts in Next.js app.

    Also, please refer to this article for more information on adding CanvasJS chart in Next.js apps.

    in reply to: Chart is cutted off at start when only axisY2 is in use #44433

    @themadmattt,

    The solution to show the label 40 depends on multiple factors based on chart-options you are using. Setting axisX viewportMinimum to a 38/39 or setting labelAngle to a positive value should work. However, these are not the limited set of solutions as we don’t know the exact use-case of yours. Kindly try out the solutions & see if it works. If you are still facing issue, kindly create a JSFiddle reproducing the issue (with sample data) & share it with us so that we can look into the chart-options being used, understand the scenario better and help you out.

    in reply to: Boxandwhisker overlapping incase of multi y axis #44408

    @heavell,

    It’s not possible to align multi-series box and whisker chart side-by-side as of now, similar to column chart. However, you can increase / decrease x-values of datapoints to achieve the same. Please take a look at this updated JSFiddle for an example on the same.

    @madsellab,

    Zooming into a region by selecting region based on taps is not available as an inbuilt feature as of now. However, you can achieve the same with few lines of code by changing the viewport based on the clicks / taps. Please take a look at this JSFiddle for an example on the same.

    in reply to: How to create detailed chart description #44170

    @hyphenfi,

    You can place an icon (info or question-mark) to the top-right of the chart & pass description as title attribute of the icon. The description will be shown in a tooltip on hovering the icon. Please take a look at this JSFiddle for an example.

    Also, you can convert it to a JavaScript function so that you can add information for multiple charts. Please refer to this JSFiddle for an example on the same.
