Column Chart scale display
Hi, I'm a spanish native speaker so I will try to make myself understood....
I'm having trouble with the "Column Chart Display" -- by that I mean:
"When you symbolize a layer with charts, a chart symbol and a number are placed in the table of contents under the layer’s name. The number next to the chart symbol represents the attribute value for a chart symbol of that size on the map. For example, a value of five means a chart on the map that is the same size as the chart in the table of contents represents 5 data units."
Ok until here I understand, but i need to adjust that number so I can compare it with other "maps charts". I haven't found the way that I can tell ArcGIS i want that 48 point column is 50.000 people, for example... so in every layer I need to compare and can say is 50.000 is the same size in every map.
It must something really easy to be done.. but I haven't found the way to do it...
Question: how does ArcGIS calculate the "Column Chart Display number"?
Thanks - hope to hear news from you.
Mapping Center Answer:
We wrote a blog entry about the chart legends -- look here for more details: Bar Chart Legends
The answer to your question is that the number next to the chart symbol in the legend relates to the value that the longest bar in the chart represents.
You cannot do much to alter the appearance of a bar chart legend, so you will have to convert it to graphics if you want to make the changes you described. Here is the online help topic for converting the legend (ands other map elements) to graphics (scroll down a bit on the page to see the section titled "Converting map elements to graphics").
