Using trendlines with datetime axis
Hi,
I am using a chart and I want to add a trendline for this chart.
I use your example: https://ej2.syncfusion.com/aspnetcore/Chart/TrendLines#/bootstrap5
And it works well.
Then I have changed the x axis for a datetime axis:
For that, I have added the value type for the x axis of the chart:
<e-chart-primaryxaxis valueType="DateTime" edgeLabelPlacement="Shift">
<e-majorgridlines width="0"></e-majorgridlines>
</e-chart-primaryxaxis>
And I have changed the series values with :
var series1 = [ { x: "2022-01-04T00:00:00", y: 0 }, { x: "2022-02-07T00:00:00", y: 1 }, { x: "2022-03-31T10:00:00", y: 2 }, { x: "2022-04-09T00:00:00", y: 3 } ];
The chart is loaded, and the trendline also:
When I use the forward forecast feature, the chart is refreshed but I don't see the trends for the new values on the graph.
To be clear, in your example, when we use the forward forecast feature, we see the trends for 2014/2015/...
Do you have an example that works with datetime x-axis?
Best regards,
Laurent
Hi Laurent,
Greetings from Syncfusion.
We suggest you to specify forecast values in milliseconds for date time axis. We have prepared sample based on your requirement. Please check with below snippet and sample.

<ejs-chart > <e-series-collection> <e-series> <e-series-trendlines> <e-trendline forwardForecast="114679000000"> </e-trendline> </e-series-trendlines> </e-series> </e-series-collection> </ejs-chart> |
