By default Pronto for Windows prints gridlines as dark grey. It is possible to modify this default behaviour by editing a setting in the windows registry.
Note that changes to the default gridline color will only affect new graphs created after the change and not any existing views.

Step 1: Check where, in the Registry, Pronto is saving its settings.

Using windows registry editor check the following location:

HKEY_LOCAL_MACHINE\SOFTWARE\Ranger\Pronto for Windows\User Info\ProfilePerUser

If the value is zero then settings are on a per machine basis and Pronto will save settings to:


If the value is not zero then settings are on a per user basis and Pronto will save its settings to:

HKEY_CURRENT_USER\SOFTWARE\Ranger\Pronto for Windows

Step 2: Ensure Pronto has saved the Graph defaults at least once.

2.1   From within Pronto for Windows select the menu item TOOLS – OPTIONS.
2.2   Select the “Graph Defaults” tab.
2.3   Change anything you like on this page and then click on OK.
2.4   Select the TOOLS – OPTIONS menu item again.
2.5   Restore whatever you changed in step 2.3 above and click OK.
2.6   Close Pronto for Windows.

Step 3: Edit the Gridline color setting in the registry.

Using Windows registry editor check the following locations, using either HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER based on the result from Step 1 above.

<xxxxxxx>SOFTWARE\Ranger\Pronto for Windows\Graphs\VertGridColour
<xxxxxxx>SOFTWARE\Ranger\Pronto for Windows\GraphsHoriGridColour

You can change either or both of these values to any number from the table below.
Note that any change made will take effect the next time Pronto for Windows is opened and a graph is created.
