c # – Embedded Graphic Database for .NET with Disk Persistence – Where Can I Find One?

I've seen very good options for Graph Database on a server for .NET, including Neo4J and OrientDB, very robust.

However, I need one integrated graph database that persists in a file on a disk so that I can easily transfer data between .NET application instances.

Something like Sqlite or LiteDB but as a database of graphs instead.

I have searched a lot with very little luck to find something important. Can any one m? Indicate one?

co.combinatorics – Polya Enumeration to study the appropriate graphic dyes

Can one use the Polya enumeration technique or its modification to evaluate the chromatic polynomial of a simple graph?

More precisely, we must make sure that two distinct points have distinct colors if they are adjacent in the simple graph, which is not guaranteed by Polya's enumeration theorem. I think that some changes in the color weighting relative to the orbits of the action of the group of automorphisms of the graph could be useful. What are the complications that follow? The Polya enumeration is used in counting the number of overlapping subgraphs, but the coloring of the graphs is something that is not usually covered. Thank you in advance.

Competition – Graphic design of the fast competition for presentation

I'm trying to create a graph to use in a presentation to compare the monolithic software architecture to the microservices architecture.

I've uploaded a model, but I want something better

It does not have to be circle-shaped, I'm open to any other configuration.

Update requirements:
IU – GUI – The UI works on the user's workstation. This is the view of the users of the application. Composed of HTML, CSS and Javascript views allowing the user to interact with the system.
Monolithic code – This runs on a single server and requires updating all the code, even when a component of the business logic needs to be changed. This business logic contains modules that fulfill a given function. You do not have to name them specifically, you can just give them a generic name and make sure that I can have up to 10 in the confinement that would represent the monolithic code.

– Graphic interface
API gateway – It could be more than one. The idea behind microservices is run on one or more different servers. The API gateway acts as a traffic flow control request that sends the request from the client's UI to the necessary Microservice. It can contain logic to send users in different directions according to certain criteria, such as you need to test a new microservice but you do not want to launch all users at the same time. The API can route the request differently
Microservices of business logic – There are complex programs consisting of one or more Atomic microservices. They constitute the business logic of the application, broken down into smaller components compared to the monolithic code, where all are in one. This can have one or more levels of services if needed.
Atomic microservices – These are small applications that work independently of each other. VS the monolithic code that the concepts of logic or business logic all run in the same application.

The API gateway and the microservices can run in an infrastructure that can run on a set of servers.

javascript – The graphic does not show up when using View-chart js in SharePoint

I have a SharePoint list and I try to view the data using Vue-chartjs. When I do it, all I get is a canvas with a grid and not a graphic being rendered. Ideas? Any help would be very appreciated. Below my code:


JS (linear graphic component)

Vue.component('my-line-chart', {
    extends: VueChartJs.Line,
    props: ('lineData', 'chartOptions'),
    mounted: function () {
        this.renderChart(this.lineData, this.chartOptions);

JS (bar graph component)

Vue.component('my-bar-chart', {
    extends: VueChartJs.Bar,
    props: ('barData', 'chartOptions'),
    mounted: function () {
        this.renderChart(this.barData, this.chartOptions);

JS (View instance)

new Vue({
  el: "#app",
  vuetify: new Vuetify(),
  data: {
    ChartConfig: {
      labels: (),
      datasets: (
          data: (),
          backgroundColor: '#3498db',
          borderColor: 'rgba(136,136,136,0.5)',
          label: "2013"
    options: {
      responsive: true,
      maintainAspectRatio: false,
      title: {
        display: true,
        text: 'Chart.js Line Chart'
      tooltips: {
        mode: 'index',
        intersect: false,
      hover: {
        mode: 'nearest',
        intersect: true
      scales: {
        xAxes: ({
          display: true,
          categoryPercentage: 0.5,
          scaleLabel: {
            display: true,
            labelString: 'Month'
        yAxes: ({
          display: true,
          scaleLabel: {
            display: true,
            labelString: 'Value'
    iceCream: (),
    drawer: false
  created: function () {
  methods: {
    getListData: function () {
      var endPointUrl = _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getbyTitle('popular ice cream')/items";

      this.status = "getting data...";
      var that = this;
      axios.get(endPointUrl).then(function (response) {
        .catch(function (error) {
    getChartData: function (chartData) {
      for (var i = 0; i < chartData.length; i++) {

      for (var i = 0; i < chartData.length; i++) {

javascript – Insert a JSON value into a Highcharts graphic

I have the following code to make a graph Highcharts:

Highcharts.chart('container', {
        chart: {
            type: 'column'
        title: {
            text: 'Browser market shares. January, 2018'
        xAxis: {
            type: 'category',
            categories: (
                'Dato #1',
        yAxis: {
            title: {
                text: '%'
        plotOptions: {
            series: {
                borderWidth: 0,
                dataLabels: {
                    enabled: true,
                    format: '{point.y:.1f}%'
        legend: {
            enabled: false
        tooltip: {
            headerFormat: '{series.name}
', pointFormat: '{point.name}: {point.y:.2f}% of total
' }, credits: { enabled: false }, series: ( { name: "DATOS", colorByPoint: true, data: ( { y: respuesta(0).ROE /*aqui deberia ingresar el valor que obtengo del json*/ } ) } ) });

Variable respuesta It's an array of JSON but when trying to enter the value of position 0 (an example in this case), I get the following error:

highcharts.src.js: 463 Error Not Captured: Error Highcharts # 14:

I did not work much with javascript and i would like to know what's going on in this problem.

Can not query with the help of the graphic page in Prometheus Web-UI

  1. Prometheus installed. Latest version 2.12
  2. Created two simple scratches.
  3. I can complete the end points and see all the detailed statistics. Awesome.
  4. I can open the Prometheus web interface and I can see that the targets are on the rise. Awesome.
  5. But when I go to the Graph screen, I immediately get an error before doing anything:
    Error loading time.
  6. Whenever I try to run a query on the Graph screen, an error occurs.

I'm checking out the Chrome Developer Console and I see this for one of the following queries:


query? query = time () & _ = 1567549812588
/ prometheus / api / v1


{"status": "error", "errorType": "bad_data", "error": "invalid parameter" query: character 1 parsing error: no expression found in the # 39; entry "}
