In Optuma it is possible to apply grid lines (like graph paper) to your chart. Options are available to allow for control of line colour, thickness and transparency for the Date and Price Major / Minor lines.
To enable the Grid Lines left-click on the Grid icon that is located in the Action Bar (far left of Optuma screen) or use the keyboard shortcut CTRL + G.
Smart Grid Lines
Optuma also has a feature called Smart Grid Lines. When this option is ticked, the grid lines will auto adjust to a "best fit" as the chart is zoomed in / out.
This should prevent scenarios where the minor grid lines cluster together as the chart is zoomed out and more data is displayed on screen leaving the overall chart view clearer.
To enabled smart grid lines right-click the Grid icon on the left side action bar and tick the Smart Grid checkbox.
