How to set markerOptions of a chart in primefacess

Primefaces uses jqplot to draw charts, but all configuration options of charts are not provided by primefaces. For example, you have a LineChartSeries object and you will draw it on a LineChartModel. There are only two configuration parameters(style and show) for marker (this option presents in LineChartSeries class) although there are more in jqplot API. What will you do if you want to set size of a marker? What about the color?
Well, there is a way to do it and it is INJECTION! When you look at it the source code you will see a json-formatted string to pass markerOptions in encode function of LineChartSeries class:


writer.write(",markerOptions:{show:" + this.isShowMarker()+ ", style:'" + this.getMarkerStyle() + "'}");
You can properly set markerStyle property whose type is String so that you can set size option when markerOptions is passed. Pay attention to single quotes. This is my injection :


myLineChartSeriesObj.setMarkerStyle("dash', size:'3.0");
Now you have just set size property of the marker. You can also set other marker options provided in jqPlot API by using this way.

Happy injection!

Integration of MuPDF Project as a Library into an Android Studio Project

I have needed to use MuPDF library in my android project. After some research, I have seen that there are many integration tutorials but, but integrated projects are developed on Eclipse. For projects on AndroidStudio+Gradle, there is no example. I mean there is no specific example which exactly refers to this issue. So, after achieving my goal, I want to share the steps publicly so that it can be reused by others.

A Way To Monetize Your Kivy Game

While I am building my game, I look for a way to monetize it. This will be my first game, so it is also the first to attempt earning money with an App. I am also not familiar to monetization companies. So, I have done a search to find an appropriate ads network which can be easily integrated with kivy . The first and only company who provides a sdk for kivy is RevMob . I integrated RevMob sdk and tested it. Unfortunately, it doesn't have a good performance and FullScreen Ads crashes. Just links will work. Therefore, RevMob option is not really preferable since ads need to be visually effective. You can also integrate android sdk of any ads network by using pyjnius . In this post, I will show how to use Adbuddiz sdk with kivy.

Encoding multi-dimensional value into 1-D with preserving closeness

After a very long time, this will be my first post. I hope that it will not be the last, and the rest will come. For a project about taxi trajectory prediction, I have applied k-NN algorithm on coordinate sequence of taxi trips. Did I have promising results? Well, it is arguable, but I have discovered some good techniques. One of them is Z-order curve (Figure 1). Figure 1: Four levels of Z-ordering (taken from Wikipedia  page) I was looking for a technique to decrease dimensionality of 2-D coordinate representation (lat-lon) into 1-D . But on this 1-D value, I would like to apply k-NN algorithm. For this purpose, 1-D values must preserve the closeness of two different coordinates. If I do linear ordering of latitude and longitude values, I couldn't achieve this goal, because closeness will depend on only one value which is placed on the right-most. Let's assume I do linear ordering as lat-lon:
