Plot discontinuous lines

Question

Hello,

I'm currently using the Chart class to plot a line chart for a time series data. However, I've encountered an issue when trying to plot a line that has gaps (i.e., discontinuous line).

Here's a simplified version of my code:

chart = Chart()
bid1_line = chart.create_line('bid1_line', width=1, color='#FF0000')
data = df[['time', 'bid1_line']].dropna()
bid1_line.set(data)

In my data, there are periods where 'bid1_line' is NaN, and I would like these periods to appear as gaps in the line chart. However, the current implementation seems to connect the points before and after the gap, creating the impression of a continuous line.

I was wondering if there's a way to create a broken line chart using the Chart class? If not, could this feature be considered for a future update?

Thank you for your help.

Hi, I also encountered the same situation. I checked and found that when I zoom in, I can occupy non continuous lines, but when I zoom out, it shows continuous lines. By the way, have you solved this problem? If there is a good solution, can you share it?

I changed the line style, still doesn't solve the problem.

nope, unfortunately, I couldn't find any solution for this behavior.

I just solved this by spliting the series, put them into two lists, and drawing them one by one using two for loops. Stupid but works.
