Color coding improvement for repeatable tasks in statistics chart

[zeradawit]

Issue Description:

The current colour scheme for repeatable tasks in the statistics chart uses only blue tones, making it difficult to distinguish between skipped and failed tasks on specific dates. To enhance clarity and provide more insightful visualizations, I propose the following improvements:

• Implement a colour palette that differentiates between skipped and failed tasks. This could involve using distinct colours (e.g., blue for completed, red for failed, and grey/non for skipped). Considering that this method applies to both negative and normal-type tasks.

• Consider a heat map visualization for count tasks. Here, colour intensity could effectively represent completion rates on specific dates. For instance, employing saturation variations within the same colour to represent completion rates (e.g., darker blue/red for higher completion rates, lighter blue/red for lower rates).
  These changes would significantly improve the usability of the statistics chart by providing users with a clearer understanding of their task completion history.

Hi, thanks for your advice!

These are all great points for improvement and we will consider it.

One point that needs to be mentioned is that the heat map UI we are currently using uses a third-party library and has some problems. We are also considering using code to implement it ourselves or introducing a better library, and then considering improving the color of the heat map.

I appreciate your consideration for this enhancement. I'm particularly interested in viewing statistical data and graphs about my performance. This would provide valuable insights into my progress and areas for improvement.
