dataframe axis

Highcharts build the Group category coordinate axis and highcharts coordinate axisHighchartsThe Group category coordinate axis further groups the category tags of the coordinate axes to form a dual-layer and multi-layer structure. This is more conducive to the presentation of data groups. To implement the Group category axis, you must use the third-party plug-in

Two days before the second generation of hardware finally to QI, roommate Fengfenghuohuo welding out two new hardware, did not think that the magnetic field generated on the circuit board than the magnetic field is also strong, resulting in the magnetic meter data changes are not obvious, we think it is welding problems (after all, datasheet said not recommended manual welding and temperature can not exceed 260 degrees), Is the pit of a roommate a hehe ~, in fact, a correction on the good.

Rdd Advantages: Compile-Time type safety The type error can be checked at compile time Object-oriented Programming style Manipulate data directly from the class name point Disadvantages: Performance overhead for serialization and deserialization Both the communication between the clusters and the IO operations require serialization and deserialization of the object's structure and data. Performance overhead of GC Frequent creation and destruction of objects is bound to increase the GC Val spa

Pandas (python) data processing: only the DataFrame data of a certain column is normalized. Pandas is used to process data, but it has never been learned. I do not know whether a method call is directly normalized for a column. I figured it out myself. It seems quite troublesome. After reading the Array Using Pandas, you want to normalize the 'monthlyincome 'column. All the online chestnuts are normalized for the entire
