【Charts】Improve Tag Name Visibility on Charts

Related products:Charts

When you hover your mouse over a chart in Charts, the tag names of the time-series data being plotted and the corresponding values are displayed. While this is a very useful feature, the information is displayed directly on top of the time-series data, which can sometimes obscure the data itself.


Although this can be avoided by moving the mouse pointer away from the chart, it does make the experience slightly less user-friendly.
Therefore, would it be possible to display the tag names in a way that minimizes overlap with the time-series data? We would appreciate it if you could look into this.

    Hi ​@Shun Takase , thank you for the clear write up and the screenshot, it makes the issue easy to see.

    If I understand correctly, when several time series sit close together, the tag name labels land on top of the lines and hide the data you are trying to read.

    I can’t say yet whether or when this will change, but we will share an update here if there is something to report. To help us understand it better: how many time series are you typically plotting when this happens, and would you prefer the names to sit outside the plot area, or to be something you can switch on and off?

    Thanks again for taking the time to share this

      Hi ​@danielferraz 
      Thank you for checking. We look forward to hearing from you if there are any updates.
      As for when this issue occurs, as a general rule of thumb, it tends to happen more frequently when there are six or more tags.
      We haven’t fully figured out the ideal solution yet, but one idea we’re considering is similar to what’s shown in the screenshot.


      The idea is to include a button that lets users toggle between the standard display and a sidebar view; when the sidebar is displayed, the tag names and values would appear in the rightmost sidebar.
      We would appreciate it if you could consider this as one possible solution.
