In my experience working with svgs is quite tricky. So what i do is usually convert them to react components using react-native-svg in combination with online SVGR tool.

simply copy paste your svg to SVGR playground input, check 'react-native' tick expand props to 'none' and copy paste the result into your code as an react component, then add props and functions etc. But delete xmlns="http://www.w3.org/2000/svg" line, this gives me errors every time for some reason.

here's an example of how svg component looks in one of my projects:

Taking a list slice has the cost O(m) where m is the size of the slice. This is because it has to create a new list of size m and populate its entries.
On the first call, the slice is of size n/2. Inside the first recursive call, the slice taken is now of size n/4. And it continues to be reduced by 1/2 on each recursive call.The total cost of taking slices is therefore: O(n/2 + n/4 + n/8 + ...) = O(n) (by taking the sum of the geometric series).

Altough it is not a react question, what you are trying to do won't work because DOM is not loaded completely when you js is read.

What you need is a load event and then load all your code there, because you have to make sure that DOM is fully loaded. Also you can make an extra check if (currentPost) to check if variable is not undefined

QUESTION

Is there an efficient way to do a vertical lookup kind of task in AWK using multiple files?

Asked 2020-Jan-10 at 10:48

I am struggling a lot with the following task which I currently try to accomplish using AWK. I am not very familiar with AWK so I am not even sure if AWK is the best for this. If this is better to be solved with Python, please let me know (but I know even less of Python).

I need to prepare an input file for an analysis which is based on collecting gene expression P-values of multiple species from different files. For each species there are multiple treatment files.

In brief: I need to collect P-values linked to sequenceIDs from multiple files and put them in a single file ordered per Orthogroup. For each Orthogroup I only need to keep the lowest P-value per species treatment file

Orthogroupfile: A list of all orthogroups: on each line one orthogroup, every column is a sequenceID, 1st column is the orthogroupID.

QUESTION

Is there an algorithm to figure out a 'nice' number formatting for a sequence of numbers of arbitrary order of magnitude?

Asked 2019-May-26 at 11:04

I'm currently using an implementation of the Extended Wilkinson Algorithm to generate a sequence of axis tick values. For this, the algorithm is given a value range [min,max] and a number n of desired tick mark values, then it outputs an array of evenly spaced values in the interval [min,max]. What I need to do is, to create String labels from these values, BUT depending on the order of magnitude of these values I would like to switch between scientific notation and decimal notation.

For example for a sequence {0.00001, 0.000015, 0.00002, 0.000025} I would like to use scientific notation {'1.0e-05','1.5e-05','2.0e-05','2.5e-05'}. For a sequence {0,8,16,24,32} I'd like to display it as decimal notation. I also don't want unnecessary trailing zeros like 0.001000 or 1.500e-05, but in case of the scientific notation example above, I want one trailing zero when other numbers need to use more decimal places. e.g. '1.00e-05' and '1.05e-05'. But wait there is more, for example for {20.0000001, 20.0000002, 20.0000003} the interesting part is of course the very small deviation of 0.0000001 for each value but 20 is still important, something like '20+1.0e-07' may be desirable because counting the zeros is tedious. Mixing scientific and decimal in the labels is also not appreciated e.g. {8000, 9000, 1.0e04, 1.1e04} is bad.

The goal is to have a consistent labeling that lets one differentiate between the values and that can be read nicely so that very small or very large values are represented in scientific notation to also save display space.

So the representation to use for a sequence does not depend on the single value itself but the whole sequence has to be taken into account. Is there a software package available or some research paper that concerns with this matter?

I have tried to implement something myself, but this does not work very well, sometimes it outputs the same strings for different numbers e.g. '86.0001', '86.0001', '86.0002', '86.0002' for {86.0001, 86.00015, 86.0002, 86.00025}.

ANSWER

Answered 2019-May-26 at 11:04

The first problem when receiving the ticks doubles is to round them with the smallest number of digits that make them distinct. This is what the below function ScaleForTicks does. If finds the largest power of 10 that can scale all ticks to integers while keeping them distinct. For ticks >= 0, scaling means dividing by the power of 10, and for ticks < 1, it means multiplying by the power of 10. Once the ticks have been scaled to integer, we round them to 0 decimals. This gives us our base labels. They still require additional processing depending on the power of 10 applied.

The question did not say how many consecutive 0's it is acceptable to have in a label. So, I added the maxZeroDigits parameter to the LabelsForTicks function. So, a label will not be displayed with scientific notation, if it contains maxZeroDigits or less consecutive 0's. Otherwise, scientific notation is used.

Another difficulty is what is illustrated by the ticks 20.0000001 20.0000002 20.0000003 in the question. The problem is to extract the common offset of all labels so as to show the actual small variation 1.0e-07 2.0e-07 3.0e-07. This problem is solved by extracting that common offset from the set of integer labels obtained after scaling. The maxZeroDigits parameter is used to determine whether to format the offset in scientific notation or not.

The question asked for fully formatted labels consisting of an optional offset, a label, and an optional exponent. Because the offset and the exponent are the same for all labels, they can be returned as separate parts. This is what the below LabelsForTicks function does. For n ticks, the first n elements of the returned array are the formatted labels without offset and exponent. The next two elements of the returned array are the label and exponent of the offset. The last element of the returned array is the exponent of the labels. The different parts may be assembled to get fully formatted labels, or they may be used separately, for example to indicate a multiplying factor (x10^2), or an offset (+1.34e+04) for the labels, along the graph axes.

Here is the code.
