As you seen from my attachment the differences of each longitude on the x axes and latitude on the y axes is not same. I would like to make it range 0.5 examples for longitude starts 112 then 112.5,then 113. and also latitude start from -6.8 then -6.85 then -6.9. I try above to edit from the legend but it has an error. Beside the range 0.5 maybe can modified the range to other 0.01. Hopefully it is possible. Because when I read the shapefile from data1 it direct show,maybe can possible to change the range of longitude and latitude.
