7. Cleaning the imageΒΆ

The next step is to clean the data image to make sure that everything that is not representing real data is removed. In our case, these are y-axes, x-axes and the outer frame. You can also use an external image editing software such as Adobe Photoshop, but we will do this now inside straditize and use some of the automatic recognition functionalities.

  1. Expand the Remove features tab

  2. Click the y-axes button, the y-axes in the plot will be highlighted

  3. Click Remove to remove them

    1. Click the x-axes button, the x-axes in the plot will be highlighted

  4. Click Remove to remove them

  5. Finally there is the right part of the diagram frame left

    For this, we use the selection toolbar:

    1. from the wand menu, select the column selection tool (click and hold the button to the right of the rect_select button in the selection toolbar to open the menu)

    2. Draw a rectangle around the right line

      and make sure you have the new-select mode activated

    3. Click the Remove button when you are done
