阅读更多关于 ElasticSearch - how to exclude filter from aggregations?

问题 I have filtered query with 3 filters: "query": "iphone", color:5, category:10, brand:25 . How can I get amount of products in each brand which have color:5 and category:10 ? In Solr I did it like: fq={!tag=tag_facet_brand}facet_brand:"564"&facet.field={!ex=tag_facet_brand}facet_brand How can I exclude 1 filter from aggregation context? (I can't use global, because I loose query:iphone , I can't use post_filter - because of performance). 回答1: We are just moving from SOLR and we are facing the

Colouring points by factor within the margin of a faceted ggplot2 plot in R

问题 I'd like to create a faceted plot with margins in ggplot2. However, I'd like the margin plot to have colours according to from which facet the particular point has been derived. It's probably best illustrated with an example: library(ggplot2) p <- ggplot(mtcars, aes(mpg, wt)) + geom_point() p + facet_grid(.~gear, margins = TRUE) Within the margin plot labelled as "(all)", I want those dots that have "gear = 3" to be plotted with one colour, those with "gear = 4" with a second colour, and

Sample code at Coliru : #include <iostream> #include <sstream> #include <string> int main() { double d; std::string s; std::istringstream iss("234cdefipxngh"); iss >> d; iss.clear(); iss >> s; std::cout << d << ", '" << s << "'\n"; } I'm reading off N3337 here (presumably that is the same as C++11). In [istream.formatted.arithmetic] we have (paraphrased): operator>>(double& val); As in the case of the inserters, these extractors depend on the locale’s num_get<> (22.4.2.1) object to perform parsing the input stream data. These extractors behave as formatted input functions (as described in 27.7

Varying axis labels formatter per facet in ggplot/R

阅读更多关于 Varying axis labels formatter per facet in ggplot/R

I have a dataframe capturing several measures over time that I would like to visualize a 3x1 facet. However, each measure contains different units/scales that would benefit from custom transformations and labeling schemes. So, my question is: If the units and scales are different across different facets, how can I specify a custom formatter or transformation (i.e., log10) to a particular axis within a facet? For example, let's say I have the data: df = data.frame(dollars=10^rlnorm(50,0,1), counts=rpois(50, 100)) melted.df = melt(df, measure.var=c("dollars", "counts")) How would one go upon
