I have a point dataset that has 18 (2 categories of 9) variables that need to be symbolized. We want to symbolize each variable using an arrowhead symbol or some kind of triangular symbol that, by adjusting angle and offset we can position around the center point, with each arrow head being a piece of a pie/pizza.
Below are some examples of how we have achieved similar outcomes with other datasets.
The above is the affect we are trying to achieve, with the exception of wanting less white space between pieces, and 9 pieces in total. This model uses symbols from the ESRI dimensioning font in the character marker symbol type. However, you are not able to adjust the size/shape of the arrowhead symbol, so cannot reduce the white area.
Below is an example using the arrow marker symbol. This provides the ability to adjust the width and length of the arrowhead along with offset and angle. So it is possible to reduce the white area between pieces. However there is no ability to provide both hollow and filled symbology.
So basically I need the best of each of these solutions, the ability to have both filled and hollow symbology, and the ability to adjust the size/shape, angle and offset of the arrowhead. Any suggestions welcome? Is it possible to easily create your own symbol? That could be the easiest way.
Just to note, the data does not allow the use of the actual pie chart symbology, hence why we are effectively making our own.
UPDATE- Attached image of representative data. If the number is greater or equal to one then is is represented with a pie piece. If it is 0 the pie piece is left out. Full pie pieces cover over hollow, so hollow will only show if full = 0 and hollow = 1 or more for the same variable/color.
