I know there have been earlier posts on this but I am new to VBA and
i am finding it difficult to find a solution for this.... i have few
charts in a sheet and its range is 1 ROW .BUT every month it keeps
increasing by 1 column. i.e if the data range for a chart is $b$7:$cm
$7 then next month it will be $b$7:$cn$7.... for all the charts in
that sheet the data range will be increased by 1 column. month is on x
axis . so charts have to get updated with every month ....... hope
anyone can give a code snippet for this.......

i.e data range for few graphs present in tat sheet

from $b$8:$cm$8 .. it will change to $b$8:$cn$8

from $b$9:$cm$9 to it will change to $b$9:$cn$9

from $b$10:$cm$10 to it will change to $b$10:$cn$10
