Why the dots in my combo chart are shown as a line chart???

Why the dots in my combo chart are shown as a line chart???

But when I chose one filter this chart can show correct.

Maybe my data points are too close to each other.

But I cannot change the raw data.

Anyone how to solve this problem? I want the chart show correctly.

Thanks in advance!

The input sheet is for the dots, and the  limit sheet is for the limit (step chart).

  I changed the scale, but it doesn't work.

I need to compare the dots and the limit (step chart), so I don't want to divide the expression axes.

Go to settings option of your qvw->User Preferences->Objects

Here set the Max Symbols in Charts as 1000.

Please find the below attachment for more information.

As Shiwani said

Go to settings option of your qvw->User Preferences->Objects

after that

Go to Chart Properties >> Presentation >> increase symbol size
