I've got a product that I've created that has 3 options available for it.
Size of the strap
Colour of the strap
Colour of the face
Now each of these are variations, but at the moment, I've got two variations on the product.
Large size, Any Strap colour, Any Face colour
Small size, Any Strap colour, Any Face colour
This allows me to change the price for the sizes for all variations.
Now the issue is that I've run out of stock of a particular face, I don't want to remove the variation, but I can't seem to add another variation saying:
Small Size, Green Strap colour, Any face colour
and make that out of stock, the first "small, any, any" variation is overwriting this & saying it's in stock.
Is there a way for me to have specific variations out of stock without having to create 170 variations covering all aspects of combinations?
If I run out of blue straps, I'd have to change the stock level of 20 variations!
Drag all global variations at the bottom of your variations, stock will be accounted for with the options, then the price will be set with the last option
The answer to this is so simple, i'm surprised it's not documented anywhere else.
For all those who will no doubt find this to be a problem, you're able to set your variations and order them to take priority by simply dragging them to the top of the list for 1st read, and the bottom of the list for last read.
At the top of your variations, put all the products that are out of stock.
Any Size, Blue Stap, Any Face
Any Size, Red Stap, Any Face
Any Size, Any Stap, Red Face
Check "Manage Stock" and put the stock to 0 for all these.
Now, lower down your list of variations, put in your global variation (The things you want applying to all the variations you're not setting manually)
Large Size, Any Colour, Any Colour
Small Size, Any Colour, Any Colour
Set the prices etc, but don't manage stock on this.
Woocommerce will then use the stock from the first variation, apply that to the product, then set the prices etc for the rest of the variations.

I'm trying to make a network-plot, and the plot is not simply straightforward (look further down for an example).
I want to plot different groups (e.g. teams) and their rating of each other. Therefore, the arrows going from one team to another should be two way (since teams can rate each other differently).
Furthermore, the teams are also rating each other internally, which means that the color of the teams should also vary depending on the rating of your own team.
Furthermore, I want to change the size of the arrows depending on the amount of collaboration.
To sum up, this is what I am seeking help to manage:
Making a two way arrows with the option to colorize the two halves of the
arrow differently depending on the rating
Colorizing the circles (i.e. the teams) depending on a team's rating of itself
The opportunity to vary the sizes of the arrows depending on the amount of collaboration
Does anyone knows how to make this plot in R?
Example of desired plot
I am working on a script for plotting volcano plots for a specific number of groups that the user specifies, i.e. if he wants to have five groups colored, the script modifies the data set accordingly with a new column called color. All the other observations that are there shouldn't be highlighted specifically, but be grey.
Is it possible to only specify the color of one group while letting ggplot2 choose all the colors for the other groups available?
I couldn't solve this using scale_color_manual, since it expects values for all groups!
This image demonstrates my problem, all other features except the groups, i.e. the "Features (all)" group should be grey instead of red, however I want ggplot to color all other groups automatically...
Specifying a custom color palette and sorting the color column solved my problem :)
I currently am one of the few R users in my company, which consists predominantly of stata users. One problem I've had with making plots using ggplot2 is that the default (theme_grey()) settings have much smaller axis font and a smaller legend than what is found in stata. Moreover, in presentations I find people have trouble reading the legend and titles from a distance.
I'm aware that ggplot2 has a theming system that allows for relative sizing. What I'd ideally like to do is to create a new default theme that I'd apply to all my plots that would make legends and axis titles larger. Importantly, however, very often the graphs I make have varying dimensions when output to pdf (e.g. 8 inch x 10 inch) or ( 10 inch x 13 inch). Since I'd like to apply this theme globally, I need it to produce good/easy to read output irrespective of the dimensions I specify when outputting to pdf.
I'd really appreciate any suggestions for how to do this/how to approach the problem using ggplot2's theming system.
Thanks!
The theme system can easily scale all the (themed) text, but not in a device sized aware way. The various theme sets, including theme_bw(), have an argument base_size which is the baseline size, in points, of fonts to use for the text. Some text is rendered at that size, and some is rendered at sizes relative to that (for example, axis labels and legend labels are rendered at 80% of the baseline size). So by specifying the base_size argument, you can scale all that text.
However, the base_size is in absolute points, not in a size which is relative to the device size. So the larger the device size, the smaller the text is relative to that.
This could be more generally be How to change the theme colours? Or maybe TA colours are not controlled by theme?
This makes bollinger bands with a nice cloud effect:
chartSeries(bars, theme="white")
addBBands()
(See example of how it looks (near the bottom) )
The cloud effect is dark grey on this next example, so almost invisible.
chartSeries(bars, theme="black")
addBBands()
How do I change it to be, say, a nice bright red, with bright purple for the upper and lower lines? (Yeah, I know, -1 for the colour scheme)
I believe I'll be able to specify an 8-hex-digit colour to specify semi-transparency. But can I do anything more exotic? E.g. it would be rather cool to use a gradient and have it #ff0000 at the centre, fading to #330000 at the upper and lower lines. Is there any gradient support in quantmod charting?
A look at chartTheme seems to indicate that a gradient is not possible, but the up/down colours can be specified, as can the respective border colours. Just define your own theme as per the examples. You can start with the predetermined theme and modify certain individual parameters.
Fleshing out Benjamin's answer and my own learnings, here is an example:
#bars is an XTS object, OHLC data
library(quantmod)
chartSeries(bars)
addBBands(n=20,sd=2)
addBBands(n=50,sd=1)
The above draws two bollinger bands, in default colour scheme. The following will change them to be a semi-transparent red (i.e. the red is stronger where they both exist):
t=chartTheme()
t$BBands$fill="#ff666633" #20% red (i.e. hex 33 is the transparency)
reChart(theme=t)
From my study of the source this should have worked to change the line colours:
t$BBands$col=c('red','blue','green')
But it does not. However you can change the top/bottom colours to the same colour with:
t$BBands$col='blue'
reChart(theme=t)
And here is how to do the same with the newer chart_series() function, and notice you can set the line colours individually (NB. there is no reChart function, as far as I can see):
t=chart_theme()
t$bbands$col$fill="#ff000033"
t$bbands$col$upper='red'
t$bbands$col$lower='green'
t$bbands$col$ma='blue'
chart_Series(bars,theme=t)
add_BBands(n=50,sd=1)
add_BBands(n=20,sd=2)
It is not possible, as far as I know, to use a different colour scheme for each of the two bollinger bands. Even changing the colour scheme like this fails, as after the second command it redraws both with the new colours!
obj=chart_Series(bars)
add_BBands(n=50,sd=1)
obj$Env$theme$bbands$col$fill="#00ff0033"
add_BBands(n=20,sd=2)
I have a large set of thumbnails I wish to display on a page (over 200). I'd like to use CSS sprites to load them to minimise the HTTP requests. I think putting all of them in one massive file is a bad idea, but splitting them into about 6 files of 40-50 thumbnails should work nicely.
All of the thumbnails are fairly low colour (can be reduced to 256 colours without quality drop), but in total all the thumbnails cover a lot more colours.
So, is there an easy way to group them based on their colour? Putting each group of files in separate folder is fine, since I can stitch together with ImageMagick or an online sprite tool later. But doing all of that in one (with CSS) would be nice too.
Update: the reason for grouping by colour:
The idea is to save more bandwidth. If I have 10 mostly-blue thumbnails, 10 green and 10 red, I can combine them to 3 images, reducing each to 256 colours. If I mix thumbnails then reducing to 256 colours makes the images poorer quality.
Firstly, I would suggest not worrying too much, and saving as a 24bit png. It may seem that the image is getting a lot bigger by doing this, but if the thumbnails are small you'll probably find that there is a large amount of bandwidth currently being using with just http headers that will go away that you can use to make your images look better.
However, if you want automate the process you could try working out the average colour (one way of doing something close to this is to resize them to 1x1, then look at the rgb colour for that pixel). Once you have a colour per images, convert to hsv and sort by hue. You can then bundle them based on that sort order. I've not actually tried this, but it may produce acceptable results.
Adjusting the number of images that get bundled will also effect the output quality. If it sucks when you put 30 images per file, try 25 and see how much difference it makes. Actually, might be smarter to think about the number of files...
Put them all into a single file.
Does it look bad, as there aren't enough colours?
add one extra file and split them equally across all the files. Goto step 2.
Well I did some testing by grabbing a sample by hand of one "tint" and comparing it to a montage created by just taking the first N images. There was only a difference of a few kilobytes, which was reduced to about 30 bytes after I found PNGcrush. Fanastic tool!
So in short, my crackpot idea has been disproven. :p
Now, this is nothing more than theoretical blabbering, but, I understand that animated GIFs have support for a distinct color palette per frame. Theoretically, you could place each image on a separate frame of the animation (leaving most of that frame transparent), and set the pause time between frames to 1ms. Set the animation to only go through once, and you could (potentially) have an effective CSS sprite with reduced to 256 colors per image.
Like I said, theoretical blabbering.
