Displaying each and every value on x-axis in Zing chart - zingchart

I have many values on x-axis and I want all the values to be displayed on the x-axis when I zoom. Is there any way to do it? As every square has no value mentioned at the bottom, so it would get difficult for the person, seeing the graph, to know which date and time that portion belongs to. You can view my graph on alnnovative.com/zing5.php and could give any suggestion too, if you think it is better to implement, in order to achieve the requirement

You'll want to use a combination of the numeric max-items & the boolean items-overlap attributes within your scale-x object to find the best way to display the information to your users. In this demo, I've reconfigured the format of the timestamps, rotated them to allow for more space, and set the previously mentioned attributes like so:
"items-overlap":true,
"max-items":20
I hope this helps! I'm on the ZingChart team as well, so please let me know if you have any other questions.

Custom markers in Excel depending on data point value

I am kind of a newbie with Excel, so asking this question here. I have already checked some videos but the examples do not fit my need, so I am wondering if this is even possible.
I have a line chart with 10 data points, and for each data point I am currently using a built-in dot marker. The data values can go from 1 to 5, which corresponds to a net promoting score where 1 is "extremely satisfied" and 5 is "extremely satisfied": I would like to have an emoticon to represent each value, e.g. sad face for 1 and happy face for 5, and have this in a systematic way, so that every chart I generate will have these custom markers displayed depending on the value.
I would go with:
having a separate sheet with a table containing the values and the related images (not sure if this is even possible)
creating some sort of magic formula to link the data value to the image
apply the magic formula to the charts
Is this approach correct? Is this even possible?
Thank you.

Excel 2010: Shading per series for Bar Charts

I have a table of data similar to this:
I want to create a bar chart like this:
But I get this:
or, when I add major gridlines, I get this:
However, I want a quick way to visually differentiate between the different quarters (Q1... Q4) by shading them with a different background color each or marking a border around them.
I don't want to export the chart as an image and edit it because:
1. This is a weekly report, it would be very repetitive and error prone.
2. It would be time consuming when I need to do it for 100s of records.
3. My manager prefers the data and the chart to be sent as part of the report. Hence, changing it to other formats is not possible.
Is it possible to create such a graph using Excel 2010? If so, how? I don't mind writing a macro for this, but am currently lost on the approach.
If you want to do something like this:
It's a bit tricky, but can be done. First you must add a fourth data series so you have the data like this:
Then you have to put the three "real" data series in the secondary axis. You must set the maximum values both in secondary and primary axes to the same value (30 in my example). Next, you delete the secondary axis. And finally, in the fourth series settings you let it overlap and put the separation to zero. Sorry, I don't know the exact english name of the settings, as my Excel is not in english.

tableau waterfall chart with mixed colors

I started working with Tableau and found out how to do waterfall charts (Gantt-charts, rolling sum for y-axis and negative value for length of bar. See here: tableau tutorial waterfall charts)
Now my question would be if there is a possibility to split the color by some category? To show what I'm talking about I set up some waterfalls with excel powerpoint. The first one without a split by a category and the second one with a split by category.
I would appreciate any help
It is as simple as dragging the right field to Color, and adjusting the table calculation.
If it's a simple running sum (for the positioning of the bar), you need to go edit the table calculation, select Compute using Advanced..., then drag all fields to addressing. Then you need to sort your data by the master field (in your case the one that has Coffee, Coke,...) maximum (ascending or descending, doesn't matter).
This way you guarantee that the running sum is being applied to one category at a time (at not one color at a time or something like that).
It's really important to understand the concept of table calculations so you can understand what's going on, how Tableau is calculating stuff. Read this http://onlinehelp.tableausoftware.com/current/pro/online/en-us/help.htm#calculations_tablecalculations_understanding_addressing.html
And if you actually understand what you're doing, it's easier to find a solution. For instance, this hack of Gantt Chart to make a waterfall. What goes on rows the chart will understand at starting point of the data, and what goes on size is, well, the size of the chart. You put negative values cause you want the bar to go down.
That being said, dragging a field to color won't mess up with the size, but it will mess up with the running sum used to determine the starting points. How to solve it? make it calculate all the colors together. How to make it? Understand table calculations and reach my solution.
This is the simple approach, if your database or fields have some peculiarity, this might not work perfectly, and you'll need to explain so I can try to understand how to solve

Grouping Series with different y-values in a scatterplot

I'm trying to group two different series that have different y values for the same x values in a scatter plot, however Excel doesn't let me do this. It wants me to put both categories in different series. Is there a way to do this?
At the moment this is about my best guess as to what you want, though I fear is not right:
Please note that an image (even a rough sketch) is often helpful when requiring a chart and that the Excel version may be relevant.

jasper reports: consistent colors in charts

I am facing this difficulty :
I want to indicate where my user is in a range of data in a chart, as well as where the average is.
That's not too difficult, that part I figured out already :)
However, if I have several charts in 1 report, my "user bar'" sometimes gets a different color, according whether it's below or above average.
This is very confusing for my users, because they can't think, let's say, "the yellow bar is always me".
The legend always has to be read, and that's not so user-friendly.
I'll illustrate the problem in an attachment.
I know how to have the same series color, but within this series, I want 1 particular color to always represent the value of the average, another to represent my user, etc.
Is this possible ?!
Thanks a lot in advance.

EDIT: I'm working with the ChartCustomizer now :
BarRenderer renderer = (BarRenderer) chart.getCategoryPlot().getRenderer();
renderer.setSeriesPaint(0, Color.blue);
renderer.setSeriesPaint(1, Color.yellow);
renderer.setSeriesPaint(2, Color.green);
renderer.setSeriesPaint(3, Color.red);
Still, this handles the series in the order they arrive from the resultset.
What I'm looking for is how I can use the series expression (as entered in 'series expression' field in the categorie series dialogue), instead of fixed indexes like 0-3.
I would suggest checking whether the sequence of your series is same in both the chart's chart data, plus color series in chart properties is also or not.
If it is same than it should print same.
