Problem using more than 12 elements in line_area graph about graphic

[entronad]

After thinking thoroughly, dimensions now has a enum type Dim instead of int [1, 2], which is always confused with [0, 1], in the new v0.7.0

Grid lines depend on ticks. How to calculate where there are ticks is called "nice number calculattion".
The current automatic nice number calculation seems not intelligent enough, we are working on it.

The temporary solution is to indicate the tick count mannually (I guess you want the first grid to align to the starting radius, so added align: 0):

'index': Variable(
  accessor: (Map map) => map['index'].toString(),
  scale: OrdinalScale(tickCount: 13, align: 0),
),

Hello my friend, thank you for your answer, effectively the points appeared after changing the ticks as you suggested, but now we have problems related to the touch.

For example in the next image if i touch the red arrow, the tooltip for the blue arrow is being displayed, this problem happens in most of the points.

You can also see the reproduction of the error in the next video:

Thank you for your help!

Please provide your specifications, especially the variables, selections and tooltip.

Your selection involves different groups and multiple variables, a little bit complex, so it may need some special indications.

Hello @entronad , as you requested, we are sending the chart and variables:

Thank you so much

The problem is dim: 0 should be dim: 1. The dim in the plane is 1 and 2, not 0 and 1.
I am also doubt which one to describe the dim is better, [1, 2] or [0, 1]?

[Kashorako]

@entronad Thank you so much for your quick answers, it's now working

Bleesings, happy new year!

The tick nice number algorithm is optimized in 0.8.0, now tickCount can be saved in this case.
