void OneDViewerData::setResult ( result_t::shared_pointer result )

set the cass data to be wrapped by this

Parameters

result the cass data to be wrapped

set the initial bounding rect in x

go through all data points of the curve and find min/max values for lin and log scale purposes

skip the check if the either coordinate of the point is not a number

find the max y value

find the min y value

find the min y value that is positive

find the min x value that is positive

void OneDViewerData::setXRangeForLog ( bool log )

set up the bounding rect for when x should be log scale

in case of log-scale: find the minimum x value that is bigger than 0 and set Left to be that value.

in case of lin-scale: set Left to the lowest value

Parameters

log	when this parameter is true the scale will be set up for log-scale otherwise for lin-scale

void OneDViewerData::setYRangeForLog ( bool log )

set up the bounding rect for when y should be log scale

in case of log-scale: find the minimum y value that is bigger than 0 and a valid number, set bottom to that value.

in case of lin-scale: set bottom to the lowest value

Parameters

log	when this parameter is true the scale will be set up for log-scale otherwise for lin-scale
