Hallo, I have 8 histograms and I want to draw them all on one canvas. This is how I’ve tackled this so far, where plane is the histogram(s).

```
//plot with points only
Callplanespoints->cd();
plane[0]->Draw("p");
plane[0]->SetMarkerStyle(8);
plane[0]->SetMarkerColor(1);
//plane[0]->SetMarkerSize(1);
for (int i=1, j=1; i<9; i++)
{
j=j+1;
plane[i]->SetMarkerStyle(8);
plane[i]->SetMarkerColor(j);
//plane[i]->SetMarkerSize(2);
plane[i]->Draw("samep");
}
```

Now I’m having a couple of problems.

- I want to fit a line to each of the histograms (plane). I want a fit that rises and then plateaus out, can some1 advice me which fit is best?
- When I use the fit panel (eg a polynomial) the original histogram is drawn , no longer just poinst.

I’m actually trying to get a histogram like the one in the following example, is there an example I can see of how to do it?

Thankyou.
