WPF centering a tooltip -


i'm new wpf , follow code explained in

how position tooltip bottom center

to center tooltip. however, received message "the resource centertooltipconverter not resolved." think should including class "centertooltipconverter" in wrong place. how or should include "centertooltipconverter" class?

thanks!

p.s.: sorry poor english.

normally ou put converter , stuff in resources section:

for example if it's usercontrol

<usercontrol.resources>     <converter:centertooltipconverter x:key="centertooltipconverter" /> </usercontrol.resources>

then post mentioned:

<multibinding converter="{staticresource centertooltipconverter}">     <binding relativesource="{relativesource self}" path="placementtarget.actualwidth"/>     <binding relativesource="{relativesource self}" path="actualwidth"/> </multibinding>

what missing xmlns-entry:

xmlns:converter="clr-namespace:yournamespace;assembly=yourassembly"

where yournamespace namespace of class centertooltipconverter

helpful links:

xaml namespaces , namespace mapping wpf xaml

xaml resources

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 .
