Bar Graph Question
Hi ECharts Team,
Would just like to ask if you have a sample or if the graph below is possible.
I was able to create this horizontal bar chart below. There are categories and each category has 2 tasks. If I pass a date value it will then fill the bar up to that date.
[cid:b52fc2fd-897b-45cb-94dd-28eb26f9d6d4]
Now let's say the task(s) has a start date and end date. I would like the bar to start and end on those dates. Please see the sample below.

Hoping to hear from your team.
Thank you,
Jon

Hi! I happened to work on a similar chart awhile back and one edge case I've run into with the stacked bar transparent series approach is when a single bar needs to span from negative to positive (see discussion here<https://github.com/apache/echarts/issues/11885#issuecomment-917510076>).
That probably doesn't apply in this case, but if needed, you can use a custom series type and encode start and end values as shown here<https://github.com/sjcobb/echarts-waterfall/blob/master/waterfall.js#L82>. I could potentially update / clean up that version and submit a PR to echarts-examples if people think it's useful.

The main idea is to create a transparent series to take the empty space so that the bars can "float".

Hi,
The doc is available at
https://echarts.apache.org/en/api.html#events.Mouse%20events.contextmenu
It should be called like
chart.on('contextmenu', function () { ... });
Thanks
