Logarithmic stacked bar charts don't draw the first dataset

[potatopeelings]

Current Behavior

With axis stacked, the first dataset is not plotted.

Steps to Reproduce (for bugs)

1. bar type
2. 2 datasets
3. y axis stacked and logarithmic (x axis needs to be stacked too, otherwise the bars won't stack)

The weird thing is that I can get a tooltip for the dataset that doesn't draw 😕

same but not the first dataset

I found it just many '65' in my case.but i just need that many '65' and want to draw it.

i found out what is wrong;

i got max value 66 and min value 65 in my datasets

but i did not set ticks.beginAtZero to true.

so it draw 65 with top=0.

i think is good to have a min top that value is not true zero

@potatopeelings you can set your data to [1000,100];

that make less distance between two values which can draw the bar

or use beginAtZero.

but i don't think this is good idea

@xmmwc - unfortunately that won't fix my issue. It's due to stacked bar charts starting from the value 0 and the fact that a logarithmic axis can't plot 0 (see jeffcarey's fix)

I believe the issue you are having is related to #3132.
