Hello guys, I am doing bachelor with huge data sets (x: 0 , 800 000) ; (y: -55, 30)

I need to change density of ticks in _x axis but even with help I could find answer. :frowning: I have never done Mathematica before and it seems little complicated for first time user. I want labels and grid to be 4x denser for better reading. Here is my graph

Instead of GridLines->Automatic try perhaps GridLines → {Range[0, 800000, 50000], Range[-55, -25, 5]}

And try including Ticks → {Range[0, 800000, 50000]}

Look up Range, GridLines and Ticks in the help system. Click on Details to see the hidden information on controlling these.

Adjust the numbers as needed

Sir, you just absolutely save my day! :slight_smile:

GridLines → {Range[0, 800, 25], Range[-100, 0, 1]}, Frame → True,
FrameTicks → {Range[0, 800,100], Range[-60, 0, 1]}

Using Range to define ticks and grids works like a charm. Could not find using of Range with Ticks and Frames in help section.

Thank you very much for your time, M.
