Customise min and max values on chart

I’d like to be able to change the minimum and maximum value of the ticks on the chart axes.

User acceptance criteria:

• By default, the range on the chart is: [min value, max value]
• if you toggle off auto-range, you get the min + max values that pop up (pre-filled with the auto-range values)
• I can set the Min + Max values for my y-axes and my x-axes
• I can only set the Min + Max values when I have numeric types on my axes (decimal, integer, float)
• I can set only my max or only my min value. If I only set the min value, then the max stays at the default max value, if I only set my max, then the min stays at the default min value.
• If a value has been formatted to a %, then I would need to set min = 0.2 to get a min value at 20%. Or, if it’s easier to have a min value = 20 to limit the % to 20%, then let’s do it that way! Basically, don’t feel like we have to add any more complexity to setting min + max values for percentages. Just use whichever of the two is easiest.

Other tasks:

• add documentation for customizing min/max values
• add tracking for customizing min/max values
  • added to lightdash_server_saved_chart_created + lightdash_server_saved_chart_updated (custom_axis_range as TRUE/FALSE)
  • created new event: lightdash_webapp_custom_axis_range_toggle_clicked

I like the way metabase does this!

Let’s say that:

• auto-range sets the range to be: [min value, max value]
• auto-range is used by default as the range in the chart
• if you toggle off auto-range, you get the min + max values that pop up (pre-filled with the auto-range values) (I’ll update the first comment with this)
