How to unlimit the number of value in time series chart

Hello There,

So this is the situation.

i have a dashboard that give me an information about connectivity from grafana to many servers. and the legend that is in the photo, I got it from the variable.

The problem is, the sum of the variable totals more than 50. when i check 12 of them, the chart didn’t show me all of the value that i checked. from above picture, i selected 15 of them but the chart just show me 10 of them. how can i remove the limit or at least increase it for example 100

i have tried this, but still not work
