Making Changes to the Canvas
To modify the canvas, make sure nothing is selected by tapping an empty area of the canvas. Then, press the Info button. The Canvas Style popover appears with the following options:
1 — Tap a chit from the displayed palette to change the canvas color or tap the rainbow chit on the right to see more color options.
2 — Change the canvas size to alter the width and height of your graph by tapping in their respective cells. (If you’d only like to customize the axes, just double-tap the last label on the axis and enter a new value; the others update accordingly.)
3 — Tap the respective axes buttons to show and hide the axes, the tickmarks, or the axis tickmark labels. To remove the name of an axis: touch and hold the axis label, then tap delete in the contextual menu.
4 — Tap the respective grid lines buttons to turn horizontal and vertical lines on and off. Grid lines emerge from the tick marks on the axes, whether the axes are visible or not.
5 — Tap the buttons to the left and right of the cell to change the grid line thickness. The button on the left decreases the thickness and the button on the right increases the thickness. Tap the cell in the center to type in a thickness.
6 — Tap a chit to change the grid color from the displayed palette or tap the rainbow chit on the right to see more color options.
