@elanchezhiyan,

With a few lines of JavaScript code, you can retain the size of the exported image with the help of devicePixelRatio. Take a look at the code-snippet given below.

chart.set("width", 1200 * (1 / window.devicePixelRatio), false);
chart.set("height", 1800 * (1 / window.devicePixelRatio));
chart.exportChart({ format: "jpg" });

Please refer to this Stackoverflow thread for more information on handling device / browser scaling in JavaScript.

@elanchezhiyan,

Based on the screenshot that you have shared, it seems like you have either set browser zoom or the scale option under display settings to 125%. In such cases, chart also gets zoomed as per your settings & exports at that particular resolution. Exporting at 100% browser & display scale settings seem to export chart at defined width & height.

However, if you like to keep browser / display scale settings at 125%, you will have to set width & height to 960×1440, so that you can export image at 1200×1800 pixels (125% of 960×1440 pixels).

@elanchezhiyan,

The solution shared by @thangaraj-raman demonstrates exporting chart with width set to 1800px & height to 1200px. You can customize the width & height of the chart as per your requirements like 1200×1800 or 1920×1080, etc. by changing the value passed in set method as shown below.

chart.set("width", 1200, false);
chart.set("height", 1800);
chart.exportChart({ format: "jpg" });

Please refer to documentation page for more customization options available along with examples that you can try out live.

@slarmon,

You can use xValueFormatString to format the x-value shown in tooltip & indexlabels. In your case, setting xValueFormatString: "HH:mm" should show just time in tooltip. Please refer to this documentation page for more information & live-example.

Andy,

The text shown in the indexlabel is getting aligned either to the left, right or center & the indexLabelTextAlign property seems to be working fine as shared in the screenshot. If you are trying to place indexlabel to the left of the marker, that’s not possible as of now. Indexlabels are placed to the center of the marker but the text within the indexlabel can be aligned to the left / right / center whenever the text is wrapped into multiple lines.

@thefireescaper,

The JSFiddle shared seems to be working fine without any error. Based on the error that you are getting, you might be passing it as ‘custombreaks’ instead of ‘customBreaks’. All the chart properties are case-sensitive. Hence passing it as customBreaks should work fine. Please refer documentation page for more information & live-examples.

If you are still facing issue, kindly create JSFiddle reproducing the issue you are facing & share it with us. From what we have observed, sometimes things get delayed mostly when we are not able to reproduce the issue at our end or not able to understand the exact requirements or due to the variation in chart-options being used by you and us. Because of these reasons we expect you so share JSFiddle along with sample data which helps us run it at our end to understand the use case and help you resolve.

Andy,

Setting indexLabelTextAlign property seems to be working fine across all the chart types including line, column, pie, etc.

Can you kindly create JSFiddle with your use-case so that we can understand the scenario better and help you out?

@eshan_23,

As addressed by @adithya-menon in the original thread, you can either use area or range-area charts to create polygon shapes. Please refer to this JSFiddle for an example on drawing hexagon using area chart.

@inferno,

It’s not possible to have different width for each column as of now.

Andrea,

You can show month names in Italian by passing month names in culture. Below is the code-snippet showing the same.

CanvasJS.addCultureInfo("it", {                  
  months: ["gennaio", "febbraio", "marzo", "aprile", "maggio", "giugno", "luglio", "agosto", "settembre", "ottobre", "novembre", "dicembre"]      
});
var chart = new CanvasJS.Chart("chartContainer", {
  culture: "it",
  .
  .
  .
}

Please take a look at this JSFiddle for an example.

@lars_,

CanvasJS Chart just renders the data that you pass in chart-options. And in case of line charts, it draws a continuous line to connect all the non-null datapoints present in a dataseries. A gap / discontinuity in the line can be observed only when there is a null datapoint with the dataseries. You can set connectNullData to true to make it continuous by connecting line between non-null data.

If this doesn’t solve in your scenario, kindly reproduce the scenario either in JSFiddle with dummy data & share it with us (or a sample project & share over Google-Drive/Onedrive) so that we can run it locally to debug & understand it better and help you out.

@reactdeveloper,

Zoom / Pan & Reset buttons will be shown when you enable zooming in the chart. If you like to enable zooming, show the buttons but disable them, you can set HTML button’s disabled property to true. Please find the code-snippet below.

var buttons = document.getElementsByClassName("canvasjs-chart-toolbar")[0].children;
for(var i = 0; i < buttons.length; i++) {
  buttons[i].disabled = true
}

However, if you like to enable zooming but hide the buttons, you can set display: none !important; to canvasjs-chart-toolbar class. Please take a look at this JSFiddle for an example.

@an01,

Y-axis scaling seems to work fine, i.e. Y-axis range (minimum & maximum) gets adjusted as per the y-values present in the viewport.

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

@nilo,

Please take a look at this gallery page for an example on rendering PHP chart with data from database. You can use multi-series chart in your case. Please take a look at this sample project for an example on rendering multi-series chart with data from database.
