Histogram - placement of bars from tick mark - not centered

Is there any way of having bars in a barseries or histogramseries (custom...) to be placed from the tickmark instead of centered around the tickmark. E.g. data 1 2 3 4 1 2 will show up as four bars placed centered around the values 1 2 3 4 http://www.epidata.dk/grafik/histogram.png I wished instead ...

Problem solved

Following the previous entry (see above) we implemented the histogram by using the addxY( ) method which in teechart results in a dataseries with an x as well as y value. In contrast to the add( ) method, which has only one count series and an x axis. Unfortunately it was not easy to take the source...

Still not fully described

We are not getting closer to a solution - unfortunately. The basic Teechart series histogram is defined as a series with three columns as you can see during the discussions above. However in the v7 Teechart documentation I found in a "strange corner", since the keyword histogram cannot be found a su...

Unfortunately not so - talvalue does not solve the problem

The "talValue" does not make it neither by setting this as: Axis.Increment := Value; Axis.LabelStyle := talValue; nor invoking the ChartEditor and in this change axis to 5 increment and Labelstyle to talValue. In both cases the axis will go from 0 to number of bins (within what fits divided by 5). T...

THistogram series bottom axis cannot change axis increment

When drawing histograms to see a distribution, say count of age for a number of persons. The histogram will draw for each age a column at the value of that age. The axis will per default show as label the value of age. Using Delphi 7 Pro and Teechart 7.07: Values are added to a histogram by these li...

Maps and shapefiles

Are there any documentation notes or further help than looking into the map example for teechart pro 7 ?

It seems very much not documented.

Also there should be possibility to use shape files from an open standard.
