Update: There is also an addon to draw polar coordinate systems.
Simply combine the unlinked clones ("star" and "bulls eye") and use the result to divide your circle. You can also combine both approaches to create a "radar". In the tab Scale, enter -100/N into the fields Scale X and Scale Y Per row (replace N with the desired number of sectors and yes, Inkscape can calculate 100/N, you don't have to use a calculator).Duplicate the circle ( ctrl+d) and click Edit > Clone > Create Tiled Clones.Divide the circle using the combined object (select both objects, ctrl+/ or Path > Division).Combine the unlinked clones ( ctrl+k or Path > Combine).Select the resulting clones and unlink them ( shift+alt+d or Edit > Clone > Unlink Clone).At the bottom of the dialog, choose Rows, columns and enter N and 1 into the related fields.In the tab Rotation, enter 360/N into the field Angle Per row (replace N with the desired number of sectors and yes, Inkscape can calculate 360/N, you don't have to use a calculator).In the tab Shift, check Exclude tile Per row.In the tab Symmetry, choose » P1: simple translation« and click Reset.Select the line and click Edit > Clone > Create Tiled Clones.A + should apear in the middle of the line. Move the rotation center of the line to the center of the circle.Ĭlick the line twice (do not double click).Draw a line from the circle's center outwards so that the line is longer than the radius of the circle.For the following steps its good to used the snapping options » center of bounding boxes«, » cusp nodes«, and » rotation center«.ĭivide circles/disks into N pie chart pieces / sectors With some effort, you can emulate the linked polar grid tool using Inkscape's tiled clones. The naive method is viable for a few cases (coarse subdivision, angles are multiples of 15°. Press ctrl while drawing the sectors to enable snapping every 15° (snapping angle can be changed in Edit > Preferences > Behaviour > Steps > Rotation snaps every.
The naive way is to use the circle tool and its sector (pie chart) mode to draw sectors with the same angle.
