pentaho - Add percentages to an OLAP cube Mondrian schema -


i calculate percentage of 1 of measures. example: have measure aggregator distinct-count. calculate percentage of measure, based on current information.

for example: gender  users-distinct-count  percentage              male    25                    25% (25/100)              female  41                    41% (41/100)              unk     34                    34% (34/100) but, if filter out unk, want percentage out of 25+41, i.e. 66               gender  users-distinct-count  percentage              male    25                    37.8% (25/66)              female  41                    %62.2 (41/66)

i want, when viewing data different dimensions, total sum updated accordingly.

i tried this:

<calculatedmember name="user_percentage" caption="users percentage"      formula="[measures].user_count/ ([measures].user_count,[dim1].[all dim1],[dim2].[all dim2])" dimension="measures" visible="true">   </calculatedmember>

but, when filtering values on dimensions (like removing "unk", total remains same (over dim).

thanks,

you should @ client level, not schema level.

the schema has no idea you're querying on rows or columns, client does.

some client tools allow create calculated measure % of visible values, has done query.

example:

with    set rowset {[gender].[male],[gender].[female]}   member [gender].[visible] aggregate( rowset, [measures].[user_count] )   member [measures].[percentage] ( [measures].[user_count], [gender].currentmember ) / ( [measures].[user_count], [gender].[vislble] )  select    rowset on rows,    { [measures][user_count], [measures].[percentage] } on columns [my cube]

as must reference set selected on rows when defining percentage, cannot define @ schema level.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
