@elanchezhiyan,

Some of the text content might look blurry because of the font-families & it’s size. I suggest you to try using Web Safe Fonts & font size that looks better as per the size of the image.

@oberfreak,

You can hide grids, ticks & axis lines by setting gridThickness, tickLength and lineThickness properties to 0. Please find the code-snippet below.

axisX:{
   gridThickness: 0,
   tickLength: 0,
   lineThickness: 0
},
axisY:{
   gridThickness: 0,
   tickLength: 0,
   lineThickness: 0
},

If you like to show axis labels inside the bar, you can do so by using labelPlacement property. Please take a look at this gallery page for an example on the same. However, if your requirement is to completely hide the axis labels & use indexlabels, you can use labelFormatter to do so. Below is the code snippet for the same.

axisX: {
    labelFormatter: function(e) {
        return "";
    }
}

Please take a look at this JSFiddle for an example on sparkline chart. Also, take a look at this Github repo for a plugin that ease your task.

@net-peretzgmail-com,

As you are passing x-values as time-stamp, it’s not considered as date-time but number. Setting interval to 1 will make chart render axis label at an interval of 1, i.e. for every 1 milliseconds and not at every 1 day. Setting xValueType: "dateTime" will convert axis into date-time axis & should work fine in this case. Also, I would suggest you to use valueFormatString to define the format of the axis label instead of using labelFormatter, unless your requirement is to completely format the axis label. Please take a look at this updated JSFiddle for the working code.

@danialtien,

X-Value can either be numeric or JavaScript date-time. In your case, it seems to be Java date-object. Passing it as timestamp as shown in this Gallery Example should work fine in this scenario.

If you are still facing issue, kindly create a sample project reproducing the issue & share it with us over Google-Drive or Onedrive so that we can run the sample locally to 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 sample project helps us in figuring out the issue and suggesting an appropriate solution accordingly.

@danialtien,

Can you kindly upload the sample project reproducing the issue you are facing to Google-Drive or Onedrive & share the link with us so that we can run it locally to understand the scenario better and help you out?

Craig Pickerill,

It looks like the sample / image provided by you is restricted and requires permission. Can you kindly make it public so that we can access it & understand the scenario to help you out?

@didileking,

With the help of get method, you can get to know the maximum of primary y-axis. Once you get the maximum of primary y-axis, you can use set method to set the maximum of secondary y-axis. Below is the code-snippet to do so.
chart.axisY2[0].set("maximum", chart.axisY[0].get("maximum"));

@mm,

Sorry for the inconvenience caused. We will fix it in our upcoming versions and we will keep you posted once the bug is fixed.

@rck,

Unfortunately, it’s not possible to have custom marker-size on hover as of now.

@rck,

By default marker borders are disabled & are not shown around the marker. Setting markerBorderThickness to a value greater than 0 will add border to the marker & makes it look bigger. Please take a look at this JSFiddle for an example on hiding markers by default but showing a bigger marker on mouse hover.

@walterschaefer,

Gridlines are drawn at every interval of the axis. Color & thickness of all the grids can be changed using gridColor & gridThickness properties respectively. As addressed earlier, you can use stripline at a particular value to show different thickness & color of a grid. Please take a look at this JSFiddle for an example.

@walterschaefer,

It’s not possible to customize the thickness & style of one particular gridline. Thickness & styling applies for all the gridlines. However, you can add stripline at specific value with custom color & thickness as per your requirements.

@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).
