asbuka,

Date-time values over y axis is not supported as of now. However, formatting the timestamp values to show it as date-time using labelFormatter should work fine in this case. Please take a look at this JSFiddle for a working example of the same.

Please refer to this article for more information about creating Gantt Charts.

@arj,

We are unable to reproduce the issue. Can you kindly create a JSFiddle (or a sample project) reproducing the issue and share it with us so that we can run it locally at our end, understand the scenario better and help you out?

@taoufiq,

It is possible to show/hide dataSeries using itemClick option in legend. Please take a look at this JSFiddle for an example of the same.

@rbadis,

chart.addTo() method is used to add the line dataseries programmatically, as shown in the example. The code you are trying does not work because the series needs to be created before “type” or “datapoints” can be assigned.

If you are looking to change the y-values such that the line is centered vertically, you can use the y-axis range to calculate the midpoint. In case you are still having issues, please create a JSFiddle and share with us, so that we can understand your scenario better and help you out.

@kkoroleva,

Setting legendMarkerType as ‘triangle’, and legendMarkerColor as ‘white’ seems to be working fine, and creates a dashed line legend marker. You can take a look this JSFiddle for the complete example.

If you are still facing any issue, please share a JSFiddle reproducing your use case, so that we can look into it and help you out.

@rbadis,

Striplines are drawn either from top to bottom, or from left to right extremes. However, you can use a line chart to achieve your requirement. Please take a look at this JSFiddle for an example of the same.

@amon75,

Please refer to this Stack Overflow thread for more information on fetching last 24 hours’ data from database. You can pass the fetched data to the chart and render it.

@netbal21,

You can get a reference to the chart instance and use it to update the data. Please take a look at this StackBlitz for an example of the same. You can also take a look at this gallery page for more examples of dynamic charts.

@scompliance,

Since the two charts have varying number of dataseries, there is a difference in datapoint width. You can use dataPointWidth property to enforce the same column width across the charts.

@scompliance,

Datapoint width depends on multiple factors including range of x-axis, number of dataseries, sequence of datapoint values, etc. Sorting the data by x-values should work in your case, and give you columns of similar width. Please take a look at this updated JSFiddle for an example of the same.

@scompliance,

Setting the stripline that is used to set the background color to be the first in the stripLines array should work fine in this case. Please take a look at this updated JSFiddle for an example of the same.

@scompliance,

Thanks for your feedback. We will add it to our wishlist. In the meantime, you can use stripline to apply background color to the plotarea as a workaround. Please refer to this JSFiddle for an example of the same.

@sujeet,

You are getting this warning because angular-charts package uses CommonJS/AMD modules. You can suppress the warning by adding it to allowedCommonJsDependencies under build options in your angular.json file, as shown below:

"build": {
    "options": {
        "allowedCommonJsDependencies": [
            "@canvasjs/angular-charts"
        ],
        ...
    },
    ...
}

Please refer to this angular documentation for more information.
