I am using the 3D Bar chart in FusionCharts. I have displayValues set to display numeric and textual values above the top of the bars. What I would like to be able to do is set the color of individual displayValues differently, for example, if the year-over-year change is positive, color the displayValue for just that bar to green, if it is negative, color it red, etc. Is this possible?
There is no direct way of coloring data plots or data values based on its value. But FusionCharts has an extensive API used to configure Annotations. You can use this API to create texts (data values). Just a rough thought came into my mind.

i am looking for a way to make a point chart based on multiple nominal conditions. i am plotting 2 values on x and y, but i would like to differentiate these points based on year as well as 'type'.
currently, the way i do it is to assign year to color while 'type' is assigned to shape
color=alt.condition(selection, alt.Color('Date:T'), alt.value('lightgray'), scheme='red' )
shape = alt.Shape('type:N')
a few questions:
is it possible to change the color scheme of the points instead of the default colors to say shades of red/blue/black, etc?
is it possible to assign one color scheme/shade (instead of shapes) to 'types'?
is it possible to change the color scheme of the points instead of the default colors to say shades of red/blue/black, etc?
Yes, see https://altair-viz.github.io/user_guide/customization.html#customizing-colors. You can use any of the built-in Vega color schemes, or define your own using the methods discussed there. From your example, it might look something like this:
color=alt.condition(
selection,
alt.Color('Date:T', scale=alt.Scale(scheme='reds')),
alt.value('lightgray')
)
is it possible to assign one color scheme/shade (instead of shapes) to 'types'?
No, there is no built-in way to apply two color scales based on two fields in the data (how would a mark choose between the two colors assigned to it?) One possible approach would be to use an opacity encoding for the second field, which is reflected in the lightness of the marks. For your example, it might look like this:
opacity='type:N'
I have a Packed Bubble dashboard. My Y axis is a list of names and my X axis is a decimal. I want each differing number to be a different color. Can I do this manually?
If you want to color each bubble with a separate color just use the field that each bubble represent in the color shelf. If I understood your data correctly, each bubble basically represents one campaign, so you should use that as the color.
You can manually assign color using Color>Edit Color and assigning the color of your choice.
See image 1.
If you want to color your bubbles based on your measure AVg(NPV/Marketing $) you can do as Alex Blakemore mentioned and use your measure as a stepped color or gradient.
You can use Color>Edit Color here too , in this case manually assigning color is a bit difficult. But if you play with number of steps, the gradient pre-select, etc, you can usually get very close to what ever your wanted it to look like.
Put your numeric field on the color shelf, and either edit the colors to use a stepped set of colors - or change the field to be discrete and choose individual colors to taste.
I need a area chart that can stylize the chart fill in a different color (red, e.g.) when this be negative.

I think the easiest way to achieve this is to create two XYCHartSeries for your Chart.
One for the negative values and one for the positives. Then you can set the color of the ChartSeries with CSS like this:
positiveChart.setId("positiveValues");
positiveChart.setStyle("#positiveValues {-fx-bar-fill: #4CAF50 }");
A data source has several columns which are ISO currency codes: USD, ZAR etc. I'd like them all to display in the same colours and share a single display.
Can tableau do this? Is there any alternative to picking my way through each column and setting every colour by hand?
You can set default colors for any field by right clicking the field and then set any color you like.Anywhere you use this field in color will have the color you chose as default
One of my uses of Kibana is related to displaying some information in certain cases only (say when a value is unexpected and exceeds a defined range). This element is therefore either shown or hidden from the dashboard, and displaying it could be considered as displaying an alert. I would prefer if the related pie chart was filled in red, rather than the default green.
Any ideas on how to do this?
Assuming you are describing Kibana 3, if you want terms panels pie charts to use different colors, you will need to make a code change.
There is a way to have custom colors for your pie chart. In order to do that you'll need to create a "hits" panel and pick the "pie chart" as the display. The color of the pie slices will be determined by the color that you chose for the queries that they track:
